Description

Description cluster: Input configuration for CH[n]

Fields

RESP

Positive channel resistor control

0 (Bypass): Bypass resistor ladder

1 (Pulldown): Pull-down to GND

2 (Pullup): Pull-up to VDD

3 (VDD1_2): Set input at VDD/2
RESN

Negative channel resistor control

0 (Bypass): Bypass resistor ladder

1 (Pulldown): Pull-down to GND

2 (Pullup): Pull-up to VDD

3 (VDD1_2): Set input at VDD/2
GAIN

Gain control

0 (Gain1_6): 1/6

1 (Gain1_5): 1/5

2 (Gain1_4): 1/4

3 (Gain1_3): 1/3

4 (Gain1_2): 1/2

5 (Gain1): 1

6 (Gain2): 2

7 (Gain4): 4
REFSEL

Reference control

0 (Internal): Internal reference (0.6 V)

1 (VDD1_4): VDD/4 as reference
TACQ

Acquisition time, the time the ADC uses to sample the input voltage

0 (3us): 3 us

1 (5us): 5 us

2 (10us): 10 us

3 (15us): 15 us

4 (20us): 20 us

5 (40us): 40 us
MODE

Enable differential mode

0 (SE): Single-ended, PSELN will be ignored, negative input to ADC shorted to GND

1 (Diff): Differential
BURST

Enable burst mode

0 (Disabled): Burst mode is disabled (normal operation)

1 (Enabled): Burst mode is enabled. SAADC takes 2^OVERSAMPLE number of samples as fast as it can, and sends the average to Data RAM.
