Figure 27. Halt mode flowchart
1. WDGHALT is an option bit. See option byte section for more details.
2. Peripherals clocked with an external clock source can still be active.
3. Only some specific interrupts can exit the MCU from Halt mode (such as external interrupt). Refer to
4. Before servicing an interrupt, the CC register is pushed on the stack. The I[1:0] bits of the CC register are

set to the current software priority level of the interrupt routine and recovered when the CC register is
popped.
