1. WDGHALT is an option bit. See
2. Peripheral 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
