AD0SC4-0: ADC0 SAR Conversion Clock Period Bits.
SAR Conversion clock is derived from system clock by the following equation, where AD0SC refers
to the 5-bit value held in bits AD0SC4-0. SAR Conversion clock requirements are given in Table 5.1.
UNUSED. Read = 0b; Write = don’t care.
AMP0GN1-0: ADC0 Internal Amplifier Gain (PGA).
00: Gain = 0.5
01: Gain = 1
10: Gain = 2
11: Gain = 4
ADC0 Data Word.
ADC0 holds the output data byte from the last ADC0 conversion. When in Single-ended mode,
ADC0 holds an 8-bit unsigned integer. When in Differential mode, ADC0 holds a 2’s complement
signed 8-bit integer.
