Note:
This instruction turns off the internal CPU clock but not the crystal oscillation. The
counter/timers and external interrupts IRQ0, IRQ1, IRQ2 and IRQ3 remain active.
The device is recovered by interrupts, either externally or internally generated. An
interrupt request must be executed (enabled) to exit HALT mode. After the inter-
rupt service routine, the program continues from the instruction after the HALT.
This instruction turns off the internal clock and external crystal oscillation and
reduces the standby current to 10 µA. The STOP mode is released by a RESET
through a Stop-Mode Recovery (pin P27). A LOW INPUT condition on P27
releases the STOP mode. Program execution begins at location 000C (Hex).
Refer to the Watch Dog Timer (WDT) section for information relating to WDT
wakeup out of Stop Mode.However, when P27 is used to release STOP mode, the

The device can be recovered by a WDT timeout. The WDT
reset in HALT Mode generates a full reset similar to the Normal
run mode (not STOP Mode).
