(2) HALT mode release
606
internal high-speed oscillation clock,
The HALT mode can be released by the following two sources.
(a) Release by unmasked interrupt request
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.
Note The wait time is as follows:
Remark
High-speed system clock,
• When vectored interrupt servicing is carried out
• When vectored interrupt servicing is not carried out
or subsystem clock
The broken lines indicate the case when the interrupt request which has released the standby
mode is acknowledged.
When main system clock is used: 10 to 12 clocks
When subsystem clock is used:
When main system clock is used: 5 or 6 clocks
When subsystem clock is used:
