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
Bit 0 = AWUEN Auto-wakeup from Halt enabled bit
Whatever the clock source, this bit should be set to enable the AWUFH mode once the
HALT instruction has been executed.
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
