6.4 WAIT Instruction
The WAIT instruction places the MCU in a low-power mode, which
consumes more power than stop mode. In wait mode, the PH2 clock is
halted, suspending all processor and internal bus activity. Internal timer
clocks remain active, permitting interrupts to be generated from the
16-bit timer and reset to be generated from the COP watchdog timer.
Execution of the WAIT instruction automatically clears the I bit in the
condition code register enabling the IRQ external interrupt. All other
registers, memory, and input/output lines remain in their previous state.
If the 16-bit timer interrupt is enabled, it will cause the processor to exit
wait mode and resume normal operation. The 16-bit timer may be used
to generate a periodic exit from wait mode. The wait mode may also be
exited when an IRQ external interrupt or RESET occurs.
