Notes: "Halted (retained)" in the table means that the internal register values are retained and
internal operations are suspended.
1. SCI enters the reset state, and other peripheral modules retain their states.
2. External interrupt and some internal interrupts (8-bit timer and watchdog timer)
3. All peripheral modules enter the reset state.
4. "Functions" or "Halted" is selectable through the setting of bits MSTPA11 to MSTPA8 in
MSTPCRA. However, pin output is disabled even when "Functions" is selected.
