A.2.3 Improved Auto Wakeup Module (AWU)
The QYxA contains an AWU that has improved accuracy across voltage and temperature for typical
testing.
A.2.3.1 Registers Affected
Setting the OSCENINSTOP bit forces the AWU to use BUSCLKX2 as the source to this timeout.
A.2.4 New Power-on Reset Module (POR)
The QYxA POR re-arm voltage will have a minimum specification of 0.7 V while the QYx Classic POR
re-arm was 0.1 V. The higher POR re-arm voltage provides added protection against brown out
conditions.

A new feature provides ability to run the AWU from an alternate source (internal oscillator or
external crystal). This is an advantage for an application that needs more accurate AWU operation.
On the QYxA AWU approximate time out will be 16 ms for short time out and 512 ms for long time
out when running from the internal 32-kHz RC source.
Finally, at lower voltages typical measurements have shown lower power consumption by the
QYxA AWU.
