Description

ADC Configuration Register 1

Fields

ADICLK

Input Clock Select

0 (00): Bus clock

1 (01): (Bus clock)/2

2 (10): Alternate clock (ALTCLK)

3 (11): Asynchronous clock (ADACK)

MODE

Conversion mode selection

0 (00): When DIFF=0:It is single-ended 8-bit conversion; when DIFF=1, it is differential 9-bit conversion with 2’s complement output.

1 (01): When DIFF=0:It is single-ended 12-bit conversion ; when DIFF=1, it is differential 13-bit conversion with 2’s complement output.

2 (10): When DIFF=0:It is single-ended 10-bit conversion ; when DIFF=1, it is differential 11-bit conversion with 2’s complement output.

3 (11): When DIFF=0:It is single-ended 16-bit conversion; when DIFF=1, it is differential 16-bit conversion with 2’s complement output.

ADLSMP

Sample time configuration

0 (0): Short sample time.

1 (1): Long sample time.

ADIV

Clock Divide Select

0 (00): The divide ratio is 1 and the clock rate is input clock.

1 (01): The divide ratio is 2 and the clock rate is (input clock)/2.

2 (10): The divide ratio is 4 and the clock rate is (input clock)/4.

3 (11): The divide ratio is 8 and the clock rate is (input clock)/8.

ADLPC

Low-Power Configuration

0 (0): Normal power configuration.

1 (1): Low-power configuration. The power is reduced at the expense of maximum clock speed.
