Port 1, 2 and 3 output drivers have internal pullup FET’s (see figure 6-5). Each I/O line can be used
independently as an input or output. To be used as an input, the port bit stored in the bit latch must
contain a one (1) (that means for figure 6-5: Q=0), which turns off the output driver FET n1. Then,
for ports 1, 2 and 3, the pin is pulled high by the internal pullups, but can be pulled low by an external
source. When externally pulled low the port pins source current (
ports are sometimes called “quasi-bidirectional”.
