Address: ADRL1, $005B; ADRL2, $005C; and ADRL3, $005D
Address:
The ADC data registers 1 to 3 (ADRL1–ADRL3), are 8-bit registers for
conversion results in 8-bit truncated mode, for channels ADC1 to ADC3,
when the ADC is operating in auto-scan mode (MODE[1:0] = 00).
The ADC auto-scan control register (ADASCR) enables and controls the
ADC auto-scan function.
