3.6 Port Functions
The TMP91C630 features 53-bit settings which relate to the various I/O ports.
As well as general-purpose I/O port functionality, the port pins also have I/O functions which
relate to the built-in CPU and internal I/Os. Table 3.6.1 lists the functions of each port pin.
Table 3.6.2 lists I/O registers and their specifications.
