SAM47 INSTRUCTION SET
NOP
— No Operation
NOP
Operation: Operand
Description: 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.
Operand
Example: Three NOP instructions follow the STOP instruction to provide a short interval for clock
stabilization before power-down mode is initiated:
