1. WDGHALT 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 an AWUFH interrupt and some specific interrupts can exit the MCU from Halt mode (such as external
4. Before servicing an interrupt, the CC register is pushed on the stack. The I[1:0] bits of the CC register are
interrupt). Refer to
set to the current software priority level of the interrupt routine and recovered when the CC register is
popped.
