ST STM32G0 1 Series User Manual

RM0444 Rev 5 393/1390
RM0444 Analog-to-digital converter (ADC)
403
15.12.7 ADC watchdog threshold register (ADC_AWD1TR)
Address offset: 0x20
Reset value: 0x0FFF 0000
Bits 31:27 Reserved, must be kept at reset value.
Bits 26:8 SMPSEL[18:0] Channel-x sampling time selection
These bits are written by software to define which sampling time is used.
0: Sampling time of CHANNELx use the setting of SMP1[2:0] register.
1: Sampling time of CHANNELx use the setting of SMP2[2:0] register.
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
Bit 7 Reserved, must be kept at reset value.
Bits 6:4 SMP2[2:0]: Sampling time selection 2
These bits are written by software to select the sampling time that applies to all channels.
000: 1.5 ADC clock cycles
001: 3.5 ADC clock cycles
010: 7.5 ADC clock cycles
011: 12.5 ADC clock cycles
100: 19.5 ADC clock cycles
101: 39.5 ADC clock cycles
110: 79.5 ADC clock cycles
111: 160.5 ADC clock cycles
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
Bit 3 Reserved, must be kept at reset value.
Bits 2:0 SMP1[2:0]: Sampling time selection 1
These bits are written by software to select the sampling time that applies to all channels.
000: 1.5 ADC clock cycles
001: 3.5 ADC clock cycles
010: 7.5 ADC clock cycles
011: 12.5 ADC clock cycles
100: 19.5 ADC clock cycles
101: 39.5 ADC clock cycles
110: 79.5 ADC clock cycles
111: 160.5 ADC clock cycles
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
