5.5.2 ADC ONE_LINE MODE (ADC_OLX)

Default = 00

Function:

These bits select which mode the ADC will use. By default one-line mode is disabled but can be se-

lected using these bits. Please see Figures 10 and 11 to see the format of one-line mode 1 and

one-line mode 2.

the DAC and ADC will be in RJ24 bits but can be set to RJ16 bits.

0 - 24 bit mode.

1 - 16 bit mode.
