Bits 5:4 – CORDYID[1:0] ADC Channel Read ID
ADCn where n= Index:
Set value to ADCn index for which status register CHNRDYDAT is going to display the current values of configuration bits and the last converted output data or written by the user to display the channel.
| Value | Description |
|---|---|
| 11 | ADC3 |
| 10 | ADC2 |
| 01 | ADC1 |
| 00 | ADC0 |
Bits 3:0 – CHRDYID[3:0] ADC Channel Read ID
Input Channel Index k:
For ADCn , set value to input channel index, k,0 ≤ k ≤ (Sn-1) for status register CHNRDYDAT to display the current values of configuration bits and the last converted output data or written by the user to display the channel.
- ADC0 supports external
analog inputs AIN0 - AIN15,
ADC1 supports external analog inputs AIN0 - AIN5 and internal AIN6 VDDCORE.
ADC2 supports external analog inputs AIN0 - AIN5 and internal AIN6 Temperature Sensor .
ADC3 supports external analog inputs AIN0 - AIN5 and internal AIN6 IVREF 1.2V .
- Selecting unimplemented input channels on a given ADCn will return a bus error with the data (32’h00000000).
