Single-chip 16-bit/32-bit microcontrollers
6.2 Pin description
Table 4. Pin description
Symbol Pin Ball Type Description
P0[0] to P0[31] I/O Port 0: Port 0 is a 32-bit I/O port with individual direction controls for each
bit. The operation of Port 0 pins depends upon the pin function selected via
the pin connect block. Pins 12, 13, 14, and 31 of this port are not available.
