Peripheral Function I/O
The I/O ports function as I/O for the peripheral functions. Peripheral function I/O may be affected by the PDi
bit of the I/O port sharing the pins. Table 14.3 lists the PDi_j Bit (i = 0 to 6, 8, j = 0 to 7) Settings when
Functioning as Peripheral Function I/O. Refer to the description of each function for information on how to set
up the peripheral functions.
The peripheral mapping controller (referred to as PMC hereafter) can be used to change the pin assignment of
I/O ports to either timer function priority or communication function priority. Changing pins must be performed
using bits PMCSEL0 to PMCSEL2 in the PMCSE register (pin assignment select register).
The 64-pin product does not have the PMC function.
Table 14.4 lists the I/O Port Pin Assignment Information by Pin Number for 64-Pin Product.
