6 I/O PORTS (PPORT)

6.7.6 Pd Port Group

The Pd port group consists of five ports Pd0–Pd4 and three ports Pd0–Pd2 are configured as a debugging function
port at initialization. These five ports support the GPIO function. The GPIO function of the Pd2 port supports out-
put only, therefore, the pull-up/down function cannot be used.
Note: The Pd3–Pd4 ports do not exist in the 32-pin package.
