DESCRIPTION
When set to '1', CH0 and CH1 operate as a differential input.
When set to '0', CH0 and CH1 operate as 2 single-ended inputs.
When bit 0 = '1', CH0 and CH1 differential inputs are setup in normal polarity mode when
this bit is set to '1', and in reverse polarity mode when this bit is set to '0'.
When bit 0 is set to “0”, this bit is ignored.
When set to '1', CH2 and CH3 operate as a differential input.
When set to '0', CH2 and CH3 operate as 2 single-ended inputs.
When bit 0 = '1', CH2 and CH3 differential inputs are setup in normal polarity mode when
this bit is set to '1', and in reverse polarity mode when this bit is set to '0'.
When bit 0 is set to “0”, this bit is ignored.
When set to '1', CH4 and CH5 operate as a differential input.
When set to '0', CH4 and CH5 operate as 2 single-ended inputs.
When bit 0 = '1', CH4 and CH5 differential inputs are setup in normal polarity mode when
this bit is set to '1', and in reverse polarity mode when this bit is set to '0'.
When bit 0 is set to “0”, this bit is ignored.
'0' must be written to this bit.
'0' must be written to this bit.

DESCRIPTION
The 10-bit ADC conversion rate for the analog inputs is set as follows:
000 = 0.512 kHz
001 = 1 kHz
010 = 1.98 kHz
011 = 3.6 kHz
100 = 6.3 kHz
101 = 9.8 kHz
110 = 13.15 kHz
111 = 13.15 kHz
The full-scale analog input range is set as follows:
000 = 2.56 V
001 = V_DD
010 = 4.096 V or V_DD (whichever is less)
011 = 2.048 V
100 = 1.024 V
101 = 0.512 V
110 = 0.256 V
111 = 0.256 V
'0' must be written to this bit.
'0' must be written to this bit.
