ST7DALIF2
Bit 2 = AWUF Auto Wake Up Flag
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
Bit 1= AWUM Auto Wake Up Measurement
This bit enables the AWU RC oscillator and connects its output to the input capture of the
12-bit Auto-Reload 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
Bit 0 = AWUEN Auto Wake Up From Halt Enabled
This bit enables the Auto Wake Up 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 Wake Up From Halt) mode disabled
1: AWUFH (Auto Wake Up From Halt) mode enabled
AWUFH prescaler register (AWUPR)
Read/Write
Reset Value: 1111 1111 (FFh)
Bits 7:0= AWUPR[7:0] Auto Wake Up Prescaler
These 8 bits define the AWUPR Dividing factor (as explained below):

In AWU mode, the period that the MCU stays in Halt Mode (t
defined by
This prescaler register can be programmed to modify the time that the MCU stays in Halt
mode before waking up automatically.
