These bits are set and cleared by software. They select the input channel to be guarded by the analog
watchdog.
00000: ADC analog input Channel 0 monitored by AWD
00001: ADC analog input Channel 1 monitored by AWD
.....
10011: ADC analog input Channel 18 monitored by AWD
other values: Reserved, must not be used
Note: The channel selected by the AWDCH[4:0] bits must be also set into the CHSELR register
Note: Software is allowed to write these bits only when ADSTART=0 (which ensures that no
conversion is ongoing).
Bits 29:24 Reserved, must be kept at reset value.
Bit 23 AWDEN: Analog watchdog enable
This bit is set and cleared by software.
0: Analog watchdog disabled
