Mode "Differential"

In mode “Differential”, all the four input pins of the GPIO are configured to receive differential signals:

Differential Signal on Pins A1/A2 (GPI 2 / GPI 3):

Differential Signal on Pins B1/B2 (GPI 0 / GPI 1)

 

Usage of pins A1 / A2 (PIN_IDs 2/3 ) and pins B1/B2 (PIN_IDs 0/1) as single-ended or differential signals
