I/O of Peripheral Functions
Input
Output
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 to 4, 6 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.
