Figure 49 : Port 8 I/O and Alternate Functions
The port structures of Port 8 differ in the way the output latches are connected to the internal bus and to
the pin driver (see the Figure 50). Pins P8.7...P8.0 (CC23IO...CC16IO) combine internal bus data and
alternate data output before the port latch input, as do the Port 2 pins.
