NOP
Function:
No operation
Description:
Execution continues at the following instruction. Affects the PC register only.
Example :
We assume we are executing an internal code and you want to produce a low–going output pulse on bit 7 of Port 2 that
lasts exactly 11 states. A simple CLR–SETB sequence generates an eight–state pulse. (Each instruction requires four
states to write to a Port SFR.) You can insert three additional states (if no interrupts are enabled) with the following
instruction sequence :
