When a lock is detected the LD bit, table 20, is set. With BLIM set to 0 the band goes from The result of the mixing is counted. A good IF count result indicates that the radio is tuned to a valid channel and not to an image or a channel with much interference. The IF counter outputs a 7bit count result via the bus.

The IF counter is continuously active and can be read at any time via the bus. It also activates a flag when the IF count result is outside the IF count valid result window. See also section 9. Before a tuning cycle is initiated the IF count period can be set to 2ms or to In case the IF count time is set to Once tuned, the IF count period is always The level voltage is analogue to digital converted with 4 bit and output via the bus.

The level ADC is continously active and can be read at any time via the bus. It also activates a flag as the Level voltages falls under a predefined selectable threshold. With the bit LHSWlarge hysteresys steps or small hyteresys steps can be chosen, according to table After completing the search algorithm and being tuned to a station, due to the hysteresis the effective limit will be set to 0.

Also with the IC in standby-mode the audio outputs are hard-muted. The audio is automatically muted during a preset as shown in the flowchart of Fig. When the audio must be muted during search mode, this must be done by setting the AFM bit before the search and resetting it afterwards. The Stereo decoder can be switched to Mono via bus. The continuous mono-to-stereo blend can also be programmed by bus to an RF level depending switched mono-to stereo transition.

The sofware port is not disabled by the PUPD bits, see section 8. The IC is still accesible via the bus, but takes only a low power from the supply, in stand-by the audio outputs are hard-muted. The power-on-reset is effectively generated by VDD. To reset these the radio must be turned on by setting PUPD[0]. The power supplies can be switched on in any order.

Different modes of operation can be selected to fit different application requirements. Up to two blocks of data and status information are available via the I 2 C-bus in a single transmission. The minimum time for detecting a pause can be adjusted by the control bits PT0 and PT1 as in table Search mode is initiated setting the SMbit to 1.

The tuner will stop on a channel with a fieldstrength equal to or higher than this reference level and then check the IF frequency, when both are valid it stops. If the level-check or the IF-count fails, it keeps on searching.

Figure 5 describes this procedure. The search algorithm can stop at a frequency which will give an offset of the IF frequency of maximum 12kHz, while applying a preset can limit the offset of the IF frequency to maximum 8kHz. It is recommended to do a preset after a search when the found frequency has an offset higher than 8kHz for the best tuning.

After this interrupt the IC will not update the tuner-registers for a period of 15ms. Table 2 shows the possible states after an autosearch or a preset. After this interrupt the IC will keep not update the tuner-registers for a period of 15ms. Table 2 shows the possible states after an autosearch or preset. When a channel is searched or a preset is done, reception can sometimes improve when injection is done at the other side of the wanted channel. During a preset the tuner is always muted, this is done by the algorithm itself.

When the AHLSI bit is set and the tuner stopped during a preset or a search because of a wrong IF count, the tuner keeps muted; this way the uP can switch the Hi-Lo setting quietly and wait for the new result. The AFM bit mutes the tuner always, independent of a search or a preset. It can be used to mute a search, by setting the AFM bit before a search is initiated and resetting it when the tuner is ready. All these mute actions are done by blocking the audio signal inside the softmute attenuator, the audio output will keep its DC level and stay low-ohmic i.

It shows the outcome of the flag register when a read is done after INTX has gone low, on condition that no other mask bits are set than shown in the table.

These alternative channel frequencies are in the RDS data, so the uP can read the alternative frequencys and store them in a memory. The tuner can do an RDS update. This is much like a preset, but with a 4ms IF count time. The tuner will jump to the alternative frequency and check the level and the IF count using a 4ms count time.

When RSSI level check is above the specified level and the IF count result is within the limits then the tuner will stay at the alternative frequency and stay muted, the uP can now decide what to do. If the Alternative Frequency is not valid it will jump back to the frequency it came from.

After this interrupt the IC will not measure the IF count for a period of 15ms. Table 3 shows the possible states after an autosearch, figure 6 the flowchart. There are two possibilities for leaving the algorithm. The tuner jumps to an alternative frequency which is not valid according to the specified SSL limit and fixed IF counter limits and jumps back, then it will automatically unmute. Or the tuner jumps to a valid alternative frequency and stays there.

Now it does not unmute. The uP can unmute or it keeps the tuner muted and can check for the presence of RDS data. The valid way to unmute is to do a preset to the current frequency at a preset an ifcount time of Unmute Activate mute Set pll to AFfreq.

When these are set they can also cause the INTX to go active HWinterrupt line depending on the status of the corresponding mask bit in table 5.

A 1 in the mask register enables the HW interrupt for that flag. Hence it is conceivable that, with all the mask bits cleared, the SWcould operate in a polling mode by continuous read operation of the interrupt flag register to look for bits being set.

Interrupt mask bits are always cleared after reading the first two bytes of the interrupt register. This is to control multiple HWinterrupts. See figure 7. It also indicates two key timing points A and B. If an interrupt event occurs while the register is being accessed after point A it must be held until after the mask register is cleared at the end of the read operation point B.

All interrupt mask bits are cleared at the end of the interrupt flag and mask bytes. Interrupt events that occur between A and B set their respective flags after the mask bits are cleared. Which means that in this picture an interrupt event occurred in period A-B, so after A-B the Flag goes high. SW writes to the mask byte and enables the required mask bits. Any flags currently set will then trigger a HW interrupt. B2 is when both registers are read and hence cleared and this is terminated by either an ack or stop bit.

If the event occurs again, before the flag is cleared, then this does not trigger any further HW interrupts until that specific flag is cleared. However two different events can occur in sequence and generate a sequence of HWinterrupts. This mode can be used for fast search tuning detection and comparison of the PI code contained in the A C -block. This mode is the standard data processing mode, if the decoder is synchronized.

An interrupt is given each time when a new block of data is decoded and when the DAVMSK is set, for details look in chapter If it is set then the decoder is synhronised, if it is 0 it is not. It will not generate a hardware interrupt.

Resetting it automatically would change the status of the ASIC and cause an automatical synschronisation search as described above. How the synchronisation is defined is explained in brief in chapter 10 and in [2].

In case of an AF update the IF count value of the alternative frequency will be in the registers, also when it jumps back, because it will then not start a new IF count.
