SFR Definition 5.2. ADC0CF: ADC0 Configuration (C8051F300/2)
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.
00: Gain = 0.5
01: Gain = 1
10: Gain = 2
11: Gain = 4
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.
