Notes:
1. WDGHALT is an option bit. See option byte sec-
tion for more details.
2. Peripheral clocked with an external clock source
can still be active.
3. Only an AWUFH interrupt and some specific in-
terrupts can exit the MCU from HALT mode (such
as external interrupt). Refer to Table 6, “Interrupt
Mapping,” on page 36 for more details.
4. Before servicing an interrupt, the CC register is
pushed on the stack. The I[1:0] bits of the CC reg-
ister are set to the current software priority level of
the interrupt routine and recovered when the CC
register is popped.
