Decfsz pic instruction

What is the relationship between the oscillator frequency of the PIC and the instruction cycle During these 4 clock pulses, the PIC will fetch the instruction that the updated Program Counter indicates PIC Instruction Set OpCode Operand Mnemonic Description RTL 34 5u, 1u RLF f, d Rotate left f d << f 30 5u, 1u RRF f, d Rotate right f d >> f 08 5u, 1u SUBWF f, d Subtract W from f d f Mid-range PICs also have an 'incfsz' instruction, equivalent to 'decfsz', except that it increments a file register instead of decrementing it. It's used in loops where you want to count up from an initial value Instruction Trace / Profiling (PIC32) Overview. Requirements for Trace. Status Affected. Notes. DECFSZ. f,d. Decrement f, Skip if 0. PIC Microcontroller and Embedded Systems branch instruction and l looping Call instruction and stack Eng. Looping in PIC. DECFSZ instruction. Repeat a sequence of instructions or a. A PIC spends its time reading instructions from the program memory, one after another, and doing whatever these instructions say. The crucial instruction here is. decfsz K,f. The PIC instruction set doesn't have much in the way of compare and branch instructions. However, the incfsz and decfsz instructions don't affect any flags.
