Syntax : DECFSZ f,d
Description : Decrements register 'f'. If 'd' is 0 the result is stored in the W register. If 'd' is 1 the result is stored back in register 'f'. If the result is 0 the next instruction is skipped. If the result is 0, the next instruction, which is already fetched, is discarded. A NOP is executed instead, making it a two cycles instruction.
