Note: This is a PPS remappable input signal. The input function may be moved from the default location shown to any PORTx pin. All output signals shown in this row are PPS remappable. This is a bidirectional signal. For normal operation, user software must map this signal to the same pin via the PPS input and PPS output registers. These pins can be configured for I²C or SMBus logic levels via the RxyI2C registers. The SCL1/SDA1 signals may be assigned to these pins for expected operation. PPS assignments of these signals to other pins will operate; however, the logic levels will be standard TTL/ST as selected by the INLVL register.
