ADC_MUXN
ADC sample time in clocks and the equivalent significant bits in the conversion.
Select ADC clock: 0 = 6 MHz, 1 = 1 MHz.
Reserved: this bit must always be set to 0.
Description
0: 32 clocks (7 bits).
1: 64 clocks (8 bits).
2: 128 clocks (9 bits).
3: 256 clocks (10 bits).
4: 512 clocks (11 bits).
5: 1024 clocks (12 bits).
6: 2048 clocks (13 bits).
7: 4096 clocks (14 bits).
Reserved: these bits must be set to 0.
Input selection for the P channel.
0x0: PB5 pin.
0x1: PB6 pin.
0x2: PB7 pin.
0x3: PC1 pin.
0x4: PA4 pin.
0x5: PA5 pin.
0x8: GND (0V) (not for high voltage range).
0x9: VREF/2 (0.6V).
0xA: VREF (1.2V).
0xB: VDD_PADSA/2 (0.9V) (not for high voltage range).
0x6, 0x7, 0xC-0xF: reserved.
Input selection for the N channel.
Refer to ADC_MUXP above for choices.
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.
