The MCU automatically provides an oscillation stabilization period t
RC
when operation switches from
watch mode to active mode. The interrupt frame period T and one of three values for t
RC
can be selected
with the miscellaneous register (MIS: $00C), as listed in figure 14.
Operation can switch directly from subactive mode to active mode, as illustrated in figure 15. In this case,
the transition time T
D
obeys the following relationship.

are applied when a 32.768-kHz crystal oscillator is used.
The value is applied only when direct transfer operation is used.
