23.3 Standby Function Operation
23.3.1 HALT mode
(1) HALT mode
The HALT mode is set by executing the HALT instruction. HALT mode can be set regardless of whether the CPU
clock before the setting was the high-speed system clock, high-speed on-chip oscillator clock, PLL clock, low-speed
on-chip oscillator clock, or subsystem clock.
The operating statuses in the HALT mode are shown below.
Caution If the interrupt mask flag is 0 (interrupt servicing enabled) and the interrupt request flag is 1
(interrupt request signal is generated), the HALT mode is released even if the HALT instruction is
executed (Because the interrupt request signal is used to release the HALT mode).
