DESCRIPTION
ADC data for port i (0≤i≤19)
• 12-bit data produced by the ADC when converting the analog input signal on port i.
• The conversion result is represented in straight binary for ports configured in single-
ended mode (modes 6, 7), and in two’s complement for ports configured as an ADC
positive input (mode 8) in differential or pseudo-differential mode (mode 9). The ADC
data register of the port configured as an ADC negative input in differential (mode 9) or
pseudo-differential mode (mode 10) contains 0x0000.
