19.2 Standby Function Operation
19.2.1 HALT mode
(1) HALT mode
594
Note 78K0/KC2-L only
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.
Address: FFA4H
Symbol
OSTS

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

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.
