22.2 Standby Function Operation
22.2.1 HALT mode
(1) HALT mode
R01UH0008EJ0401 Rev.4.01
Jul 15, 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.
Note The 78K0/KB2 is not provided with a subsystem clock.
Address: FFA4H
Symbol
OSTS

Cautions 1. To set the STOP mode when the X1 clock is used as the CPU clock, set OSTS before

time set by OSTS. If the STOP mode is entered and then released while the internal
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.
