PPS selections for peripherals with bidirectional signals on a
single pin must be made so that the PPS input and PPS output select the same pin. The
I2C Serial Clock (SCL) and Serial Data (SDA) are examples of such pins.
Important: The I2C
default pins and a limited number of other alternate pins are I2C and SMBus compatible. SDA and SCL signals can be routed to any pin; however,
pins without I2C compatibility will operate at standard
TTL/ST logic levels as selected by the port’s INLVL register.
