Port 3 is a 7-bit I/O port with output latch. P30 to P36 pins can specify the input mode/output mode in 1-bit units
This port has the following functions for pull-up resistors. These functions differ depending on port’s bits location
The P30 to P33 pins can drive LEDs directly.
The P32 and P33 pins can also be used for serial interface data I/O and clock I/O.
RESET input sets port 3 to input mode.
Figures 6-12 to 6-15 show block diagrams of port 3.
