When deep standby mode is canceled by NMI interrupt or IRQ interrupt, reset exception
handling is executed instead of interrupt exception handling. These are power-on reset
exception handlings including a manual reset.
RTC operates when the START bit in the RCR2 register is set to 1. For details, see
section 15, Realtime Clock (RTC).
