ADC offset register (ADC_OFFSET)
Address offset: 0xD008
Reset value:
Bit 2 ADC_1MHZCLK: Select ADC clock:
Bit 1 Reserved: this bit must always be set to 0.
Bit 0 ADC_ENABLE: Enable the ADC: write 1 to enable continuous conversions, write 0 to stop.

0x0: PB5 pin.0x8: GND (0V) (not for high voltage range).
0x1: PB6 pin.0x9: VREF/2 (0.6V).
0x2: PB7 pin.0xA: VREF (1.2V).
0x3: PC1 pin.0xB: VREG/2 (0.9V) (not for high voltage range).
0x4: PA4 pin.0x6, 0x7, 0xC-0xF: Reserved.
0x5: PA5 pin.
Refer to ADC_MUXP above for choices.
0: 6 MHz1: 1 MHz.
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.
gain correction is applied.
