(2) HALT mode release
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
The HALT mode can be released by the following two sources.
(a) Release by unmasked interrupt request
internal high-speed oscillation clock,
When an unmasked interrupt request is generated, the HALT mode is released. If interrupt acknowledgment is
enabled, vectored interrupt servicing is carried out. If interrupt acknowledgment is disabled, the next address
instruction is executed.
Notes 1. The wait time is as follows:
Remark The broken lines indicate the case when the interrupt request which has released the standby mode is
High-speed system clock,
or subsystem clock
2. The 78K0/KB2 is not provided with a subsystem clock.

• When vectored interrupt servicing is carried out:
• When vectored interrupt servicing is not carried out: 4 or 5 clocks
