Bit 31 Reserved, must be kept at reset value.
Bits 30:26 AWD1CH[4:0]: Analog watchdog channel selection
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
.....
10001: ADC analog input Channel 17 monitored by AWD
10010: ADC analog input Channel 18 monitored by AWD
Others: Reserved
Note: The channel selected by the AWDCH[4:0] bits must be also set into the CHSELR
register.
The software is allowed to write this bit only when ADSTART bit is cleared to 0 (this
ensures that no conversion is ongoing).
Bits 25:24 Reserved, must be kept at reset value.
Bit 23 AWD1EN: Analog watchdog enable
This bit is set and cleared by software.
0: Analog watchdog 1 disabled
1: Analog watchdog 1 enabled

ensures that no conversion is ongoing).
Bit 22 AWD1SGL: Enable the watchdog on a single channel or on all channels
This bit is set and cleared by software to enable the analog watchdog on the channel
identified by the AWDCH[4:0] bits or on all the channels
0: Analog watchdog 1 enabled on all channels
