(a) Release by unmasked interrupt request
Note Only when sets count clock to f
Note The operation stop time is 17 s (MIN.), 34 s (TYP.), and 67 s (MAX.).
Remark The broken lines indicate the case when the interrupt request that has released the standby mode is
When an unmasked interrupt request (8-bit timer H1
generated, the STOP mode is released. After the oscillation stabilization time has elapsed, if interrupt
acknowledgment is enabled, vectored interrupt servicing is carried out. If interrupt acknowledgment is
disabled, the next address instruction is executed.
