13. PORT FUNCTIONS
{ Number of ports
Dedicated input ports: 9
Input/output ports:
114
{ Shares pins with other peripheral function I/O
{ Input and output can be specified in 1-bit units
The block diagrams of the various ports are divided into 16 block types identified by A to P as shown in Table 13-
1. Figures 13-1 to 13-16 show the block diagrams of each type.
