15.7.4 ADC Auto-Scan Mode Data Registers (ADRL1–ADRL3)
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).
15.7.5 ADC Auto-Scan Control Register (ADASCR)
The ADC auto-scan control register (ADASCR) enables and controls the ADC auto-scan function.
