(2) HALT mode release
40 MHz internal high-speed oscillation clock,
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
2. The 78K0R/IB3 doesn’t have the subsystem clock.
High-speed system clock,
• When vectored interrupt servicing is carried out
• When vectored interrupt servicing is not carried out
The broken lines indicate the case when the interrupt request which has released the standby
mode is acknowledged.
