NOP
Operation:
Description:
Example:
No operation is performed by a NOP instruction. It is typically used for timing delays.
One NOP causes a 1-cycle delay: with a 1 µs cycle time, five NOPs would therefore cause a 5 µs
delay. Program execution continues with the instruction immediately following the NOP. Only the
PC is affected. At least three NOP instructions should follow a STOP or IDLE instruction.
Three NOP instructions follow the STOP instruction to provide a short interval for clock
stabilization before power-down mode is initiated:
