ADC_PERIOD: ADC sample time in clocks and the equivalent significant bits in the conversion.
0: 32 clocks (5 bits).4: 512 clocks (9 bits).
1: 64 clocks (6 bits).5: 1024 clocks (10 bits).
2: 128 clocks (7 bits).6: 2048 clocks (11 bits).
3: 256 clocks (8 bits).7: 4096 clocks (12 bits).
ADC_HVSELP: Select voltage range for the P input channel.
0: Low voltage range (input buffer disabled).
1: High voltage range (input buffer enabled).
ADC_HVSELN: Select voltage range for the N input channel.
0: Low voltage range (input buffer disabled).
1: High voltage range (input buffer enabled).
Note: For the STM32W108CC and STM32W108CZ, the HVSELN register allows the chopper
to be controlled.
ADC_MUXP: Input selection for the P channel.
0x0: PB5 pin.
0x1: PB6 pin.
0x2: PB7 pin.
0x3: PC1 pin.
0x4: PA4 pin.
0x5: PA5 pin.
ADC_MUXN: Input selection for the N channel.
Refer to ADC_MUXP above for choices.
ADC_1MHZCLK: Select ADC clock:
0: 6 MHz1: 1 MHz.
Reserved: this bit must always be set to 0.
ADC_ENABLE: Enable the ADC: write 1 to enable continuous conversions, write 0 to stop.
When the ADC is started the first conversion takes twice the usual number of clocks plus 21
microseconds. If anything in this register is modified while the ADC is running, the next
conversion takes twice the usual number of clocks.
