Voltage
Reference
(3)
VREF+ 24 43 27 26 I/O
Voltage reference (VREF) power supply - external
reference input / internal reference output
VREF- 17 39 25 24 I/O
Voltage reference (VREF) ground supply - external
reference input / internal reference output
(1) – = not available
(2) I = input, O = output, I/O = input or output, P = power
(3) When using VREF+/- to bring in an external voltage reference for analog peripherals such as the ADC, a decoupling capacitor must be
placed on VREF+ to VREF-/GND with a capacitance based on the external reference source
