NOTES
1. If the CLKOUT pin is not used, turn it OFF, using CLKODIS in SPORT0 autobuffer control register.
2. If 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 inter-
3. All bidirectional pins have three-stated outputs. When the pin is configured as an output, the output is Hi-Z (high impedance) when inactive.
4. CLKIN, RESET, and PF3:0/MODE D:A are not included in the table because these pins must be used.

Hi-Z = High Impedance.
rupts 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.
