A/D Conversion Start
1 = Conversion start.
0 = Conversion stopped and A/D converter enter idle state.
ADST bit can be set to 1 from two sources: software write and external pin
STADC. ADST is cleared to 0 by hardware automatically at the ends of single
mode and single-cycle scan mode on specified channels. In continuous scan
mode, A/D conversion is continuously performed sequentially until software
write 0 to this bit or chip reset.
A/D Differential Input Mode Enable
1 = A/D is in differential analog input mode
0 = A/D is in single-end analog input mode
Differential input voltage (V
Note: In differential input mode, only one of the two corresponding channels
needs to be enabled in ADCHER. The conversion result will be placed to the
corresponding data register of the enabled channel. If both channels of a
differential input paired channel are enabled, the ADC will convert it twice in
scan mode. And then write the conversion result to the two corresponding data
registers.

External Trigger Enable
Enable or disable triggering of A/D conversion by external STADC pin.
1= Enable
0= Disable
