ST STM32G4 Series Reference Manual page 662

Analog-to-digital converters (ADC)
Bits 31:27 Reserved, must be kept at reset value.
Bits 26:0 SMPx[2:0]: Channel x sampling time selection
These bits are written by software to select the sampling time individually for each channel.
During sampling cycles, the channel selection bits must remain unchanged.
000: 2.5 ADC clock cycles
001: 6.5 ADC clock cycles
010: 12.5 ADC clock cycles
011: 24.5 ADC clock cycles
100: 47.5 ADC clock cycles
101: 92.5 ADC clock cycles
110: 247.5 ADC clock cycles
111: 640.5 ADC clock cycles
Note: The software is allowed to write these bits only when ADSTART=0 and JADSTART=0

Bits 31:28 Reserved, must be kept at reset value.
Bits 27:16 HT1[11:0]: Analog watchdog 1 higher threshold
These bits are written by software to define the higher threshold for the analog watchdog 1.

AWD2CH, AWD3CH, AWD_HTx, AWD_LTx, AWDx)
Note: The software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which
ensures that no conversion is ongoing).
