38.4 Signal Description
| Signal | Type | Description |
|---|---|---|
| AVDD | Power | Analog Power Supply |
| AVSS | Power | Analog Ground Supply |
| ADC_VREFH | Reference | External voltage reference |
| ADC AINx, x =0,1,,…,11 | Analog | AINx Analog inputs for ADC Module 0 |
Note:
- Channel 12 is attached internally to the Temperature Sensor Monitor.
- Channel 13 is attached internally to the IVREF, Band Gap 1.2 Volt Monitor.
Note: Please consult the section “Signal
Description” and “ADC Pinout I/O Description” table to determine which pins provide
which input signals, depending on the device package in use.
All the AINx signals listed above can be used for single-ended input and/or 3 for differential inputs pairs.
- (ADC_AIN0 (Diff +) , ADC_AIN1 (Diff -) )
- (ADC_AIN2 (Diff +) , ADC_AIN3 (Diff -) )
- (ADC_AIN4 (Diff +) , ADC_AIN5 (Diff -) )
These pairs are configured in the CHNCFG3n (n=1,2,3) register by setting the DIFF bits corresponding to the signal pairs in use.
