Check:
The external reset caused neither in the normal operating state (RUN) nor sleep state in
main clock mode must remain input until oscillation of the main clock becomes stable.

main clock mode
(1) STBC : SLP= "1"
(2) Interrupts (various types)
(3) External reset
(4) STBC : STP="1"
(5) External interrupt
(6) End of main clock oscillation

Standby control register
Transition to watch mode is enabled only from sub-RUN state (SYCC: SCS = "0").
