(2) HALT mode release

20 MHz 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.
Notes 1. The wait time is as follows:
Remark
internal high-speed oscillation clock,
2. The 78K0R/KC3-L (40-pin) doesn’t have the subsystem clock.
The broken lines indicate the case when the interrupt request which has released the standby mode is
acknowledged.
