Auto Wakeup Module (AWU)
4.1 Introduction
This section describes the auto wakeup module (AWU). The AWU generates a periodic interrupt during
stop mode to wake the part up without requiring an external signal. Figure 4-1 is a block diagram of the
AWU.

4.2 Features
Features of the auto wakeup module include:
One internal interrupt with separate interrupt enable bit, sharing the same keyboard interrupt vector
and keyboard interrupt mask bit
Exit from low-power stop mode without external signals
Selectable timeout periods
Dedicated low-power internal oscillator separate from the main system clock sources
Option to allow bus clock source to run the AWU if enabled in STOP
