These 8 bits define the AWUPR Dividing factor (see
dividing
This bit is set by hardware when the AWU module generates an interrupt and
cleared by software on reading AWUCSR. Writing to this bit does not change its
value.
0: No AWU interrupt occurred
1: AWU interrupt occurred
This bit enables the AWU RC oscillator and connects its output to the input capture
of the 8-bit Lite timer. This allows the timer to be used to measure the AWU RC
oscillator dispersion and then compensate this dispersion by providing the right
value in the AWUPRE register.
0: Measurement disabled
1: Measurement enabled
This bit enables the Auto-wakeup From Halt feature: once Halt mode is entered, the
AWUFH wakes up the microcontroller after a time delay dependent on the AWU
prescaler value. It is set and cleared by software.
0: AWUFH (Auto-wakeup From Halt) mode disabled
1: AWUFH (Auto-wakeup From Halt) mode enabled
Note: Whatever the clock source, this bit should be set to enable the AWUFH
