DESCRIPTION
ADCDAT_0[11:0]
ADC data for port i (0≤i≤11)
ADCDAT_1[11:0]
• 12-bit data produced by the ADC when converting the analog input signal on port i.
ADCDAT_2[11:0]
• The conversion result is represented in straight binary for ports configured in single-
ADCDAT_3[11:0]
ended mode (modes 6, 7), and in two’s complement for ports configured as an ADC
ADCDAT_4[11:0]
positive input (mode 8) in differential or pseudo-differential mode (mode 9). The ADC
ADCDAT_5[11:0]
11:0
ADCDAT_6[11:0]
data register of the port configured as an ADC negative input in differential (mode 9)
or pseudo-differential mode (mode 10) contains 0x0000.
