No operation
Execution continues at the following instruction. Other than the PC, no registers or
flags are affected.
It is desired to produce a low-going output pulse on bit 7 of port 2 lasting exactly
5 cycles. A simple SETB/CLR sequence would generate a one-cycle pulse, so four
additional cycles must be inserted. This may be done (assuming no interrupts are
enabled) with the instruction sequence
