Single-chip 16/32-bit microcontrollers
5.2 Pin description
Table 3. Pin description
Symbol Pin 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. Total of
31 pins of the Port 0 can be used as a general purpose bidirectional digital I/Os while
P0.31 is output only pin. The operation of port 0 pins depends upon the pin function
selected via the pin connect block.
Pin P0.24 is not available.
