Table 20. Port Operating Mode Settings
Note: 1. N/A = Not Applicable
2. The direction of the Port A,B,C, and D pins are controlled by the Direction Register ORed with the individual output enable product
term (.oe) from the CPLD AND Array.
3. Any of these three methods enables the JTAG pins on Port C.
