Notes amended
Notes: 1. A transition between different modes cannot be
made to occur simply because an interrupt request is
generated. Make sure that interrupts are enabled.
Note amended
Note:
If an external clock is being input, set standby timer select to
external clock mode before mode transition. Also, do not set
standby timer select to external clock mode if no external clock
is used. 8,192 states (STS2 = STS1 = STS0 = 0) is
recommended if the on-chip oscillator is used on the H8/38124
Group.
