The
μ
PD17215 oscillator circuit is stopped, when the STOP instruction has been executed (i.e., in the STOP mode).
Oscillation is not resumed, until the STOP mode is released. After the STOP mode has been released, the HALT mode
is set. Set the time required to release the HALT mode by using the timer with modulo function.
The time that elapses, after the STOP mode has been released by occurrence of an interrupt, until an operation mode
is set, is shown in the following table.

Remark:
Set the 8-bit modulo timer before executing STOP instruction.
Caution:
Do not execute an instruction that clears the interrupt request flag (IRQxxx) for which the
interrupt enable flag (IPxxx) is set immediately before the STOP 8H instruction; otherwise, the
STOP mode may not be set.
