18.2.2 STOP mode
(1) STOP mode setting and operating statuses
906
The STOP mode is set by executing the STOP instruction, and it can be set only when the CPU clock before the
setting was the internal high-speed oscillation clock, X1 clock, or external main system clock.
Cautions 1. Because the interrupt request signal is used to clear the standby mode, if there is an
The operating statuses in the STOP mode are shown below.
2. The STOP instruction cannot be executed when the CPU operates on the 40 MHz internal
interrupt source with the interrupt request flag set and the interrupt mask flag reset, the
standby mode is immediately cleared if set. Thus, the STOP mode is reset to the HALT
mode immediately after execution of the STOP instruction and the system returns to the
operating mode as soon as the wait time set using the oscillation stabilization time select
register (OSTS) has elapsed.
high-speed oscillation clock. Be sure to execute the STOP instruction after shifting to
internal high-speed oscillation clock operation.
