Input
Output
I/O of Peripheral Function
I/O ports function as I/O ports for peripheral functions (refer to Table 1.4 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 = 1, 3, 4, j = 0 to
7).
Refer to the description of each function for information on how to set peripheral functions.
Figure 7.8 shows the Configuration of I/O Pins.

Pins Other than I/O Ports
(i = 1, 3, 4, j = 0 to 7)
Setting of PDi_j Bit when Functioning as I/O Ports for Peripheral Functions
Set this bit to 0 (input mode).
This bit can be set to either 0 or 1 (output regardless of the port setting).
