How to perform software standby mode?

Latest Updated:06/20/2013

Question:

I cannot enter software standby mode. (I cannot enter deep software standby mode.)

Answer:

When the oscillation stop detection function enable bit (OSTDCR.OSTDE) is 1 (oscillation stop detection function is enabled), software standby mode and deep software standby mode cannot be entered. To enter software standby mode or deep software standby mode, set the OSTDE bit to 0 (oscillation stop detection function is disabled) before executing a WAIT instruction.

For details, see "Oscillation Stop Detection Control Register (OSTDCR)" in the "Clock Generation Circuit" chapter in the user's manual: hardware.
