Description

Status and Control Register 3

Fields

ADICLK

Input Clock Select

0 (00): Bus clock

1 (01): Bus clock divided by 2

2 (10): Alternate clock (ALTCLK)

3 (11): Asynchronous clock (ADACK)

MODE

Conversion Mode Selection

0 (00): 8-bit conversion (N = 8)

1 (01): 10-bit conversion (N = 10)

2 (10): 12-bit conversion (N = 12)

ADLSMP

Long Sample Time Configuration

0 (0): Short sample time.

1 (1): Long sample time.

ADIV

Clock Divide Select

0 (00): Divide ration = 1, and clock rate = Input clock.

1 (01): Divide ration = 2, and clock rate = Input clock * 2.

2 (10): Divide ration = 3, and clock rate = Input clock * 4.

3 (11): Divide ration = 4, and clock rate = Input clock * 8.

ADLPC

Low-Power Configuration

0 (0): High speed configuration.

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