4. Port Function

The TMP91CW60 features 83 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 4-1 lists the functions of each port pin. Table 4-1 lists the functions of each port pin.

Table 4-2 lists I/O registers and their specifications.
