Figure 23. Halt timing overview
1. A reset pulse of at least 42µs must be applied when exiting from Halt mode.
Figure 24. Halt mode flowchart
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 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 bit of the CC register is set
5. The CPU clock must be switched to 1 MHz (RC/8) or AWU RC before entering Halt mode.
Table 9: Interrupt mapping
