@edeca: I work on my own code now and found almost all ASM instructions only use 1 cycle for the 12F683. What do I overlook? If each of my ASM instructions that I need to generate the ID indeed only use a single cycle, do I understand correct for 5MHz clock I may use 4 instructions? The instructions outise the period were the ID is generated towards the GPIO may use more instructions as this is just for generating the random interval in between the sending of the ID's. Can you respond to me?

@edeca: Already solved, each ASM instruction is executed by an Internal instruction cycle clock which is FOSC/4.
This indeed puts some pressure in being creative to set the GPIO in as less as possible ASM instructions...
No need to reply anymore!
