Wait Mode
When the MCU enters the Wait mode, the CPU clock is halted. All CPU activities and the
DTMF/Melody Generation are halted, as in Stop mode; however, the timers (A and B) and SPI
system remain active. An interrupt from the timer, keyboard, SPI, or IRQ1/IRQ2 causes the
processor to exit the Wait mode. A reset will also take the MCU out of Wait mode.
The operation of the COP system in Wait mode is as for Stop mode.
The Wait mode power consumption depends on how many systems are active. The power
consumption will be the least when the SPI and timer are disabled. If a non-reset exit from the Wait
mode is performed (e.g. timer overow interrupt exit), the state of the remaining systems will be
unchanged. If a reset exit from the wait mode is performed, all the systems revert to the disabled
reset state.
