The port structures of Port 7 differ in the way the output latches are connected to the internal bus and to
the pin driver (see the two Figure 47). Pins P7.3...P7.0 (POUT3...POUT0) XOR the alternate data output
with the port latch output, which allows to use the alternate data directly or inverted at the pin driver.
