7. Programmable I/O Ports
7.2 Effect on Peripheral Functions
Programmable I/O ports function as I/O ports for peripheral functions (refer to Table 1.6 Pin Name Information
by Pin Number).
Table 7.3 lists the Setting of PDi_j Bit when Functioning as I/O Ports for Peripheral Functions (i = 0, 1, 3 to 5, j =
0 to 7). Refer to the description of each function for information on how to set peripheral functions.

I/O of Peripheral Functions
PDi_j Bit Settings for Shared Pin Functions
Input
Set this bit to 0 (input mode).
Output
This bit can be set to either 0 or 1 (output regardless of the port setting)
7.3 Pins Other than Programmable I/O Ports
Figure 7.7 shows the Configuration of I/O Pins.
