Register description
AWUFH control/status register (AWUCSR)
Reset value: 0000 0000 (00h)
Bits 7:3 = Reserved.
Bit 2= AWUF Auto-wakeup flag
Bit 1= AWUM Auto-wakeup measurement
Bit 0 = AWUEN Auto-wakeup from Halt Enabled
This bit is set by hardware when the AWU module generates an interrupt and cleared
by software on reading AWUCSR.
0: No AWU interrupt occurred
1: AWU interrupt occurred
This bit enables the AWU RC oscillator and connects internally its output to the ICAP2
input of 16-bit timer A. 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 AWUPR 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 defined by 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
