Notes:
1. EXCTNL is an option bit. See option byte section for more details.
2. Peripheral clocked with an external clock source can still be active.
3. Only some specific interrupts can exit the MCU from STOP mode (such as external interrupt). Refer to
the Interrupt Mapping table for more details.
