19.2 Standby Function Operation
19.2.1 HALT mode
(1) HALT mode
R01UH0028EJ0400 Rev.4.00
Sep 27, 2010
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, internal high-speed oscillation clock, or subsystem clock
The operating statuses in the HALT mode are shown below.

high-speed oscillation clock is being used as the CPU clock, set the oscillation
stabilization time as follows.
Note, therefore, that only the status up to the oscillation stabilization time set by
OSTS is set to OSTC after STOP mode is released.
