When the pin is configured as an output, the output is Hi-Z (high impedance) when inactive. 3Hi-Z = High Impedance. 4If the CLKOUT pin is not used, turn it OFF, using CLKODIS in SPORT0 autobuffer control register. 5If the Interrupt/Programmable Flag pins are not used, there are two options: Option 1: When these pins are configured as INPUTS at reset and function as interrupts and input flag pins, pull the pins High (inactive). Option 2: Program the unused pins as OUTPUTS, set them to 1 prior to enabling interrupts, and let pins float. Table 5.
