I/O Ports
They can be individually programmed as general-purpose I/O or dedicated I/O for the on-chip CPU or
peripherals. Table 7.1 shows all the I/O port pins available on the TMP1940CYAF and their shared functions.
(There is no Port 6.) Table 7.2 is a summary of register settings used to control the port pins.
The TMP1940CYAF has 77 I/O port pins. All the port pins except a few share pins with alternate functions.
