AWUIE — Auto Wakeup Interrupt Enable Bit
4.6.4 Configuration Register 2
The configuration register 2 (CONFIG2), is used to allow the bus clock source to run in STOP. In this case,
the clock, BUSCLKX2 will be used to drive the AWU request generator.
OSCENINSTOP — Oscillator Enable in Stop Mode Bit
4.6.5 Configuration Register 1
The configuration register 1 (CONFIG1), is used to select the period for the AWU. The timeout will be
based on the COPRS bit along with the clock source for the AWU.
Freescale Semiconductor
This read/write bit enables the auto wakeup interrupt input to latch interrupt requests. Reset clears
AWUIE.
OSCENINSTOP, when set, will allow the bus clock source (BUSCLKX2) to generate clocks for the
AWU in stop mode. See
external clock sources.
1 = Auto wakeup enabled as interrupt input
0 = Auto wakeup not enabled as interrupt input
1 = Oscillator enabled to operate during stop mode
0 = Oscillator disabled during stop mode
