8.4
Port 3 is an 8-bit I/O port. Port 3 pins also function as a bidirectional data bus, XBS bidirectional
data bus, and LPC input/output pins. Port 3 functions change according to the operating mode.
Port 3 has the following registers.
8.4.1
P3DDR specifies input or output for the pins of port 3 on a bit-by-bit basis.

Description
Modes 1, 2, and 3 (EXPE = 1)
The input/output direction specified by P3DDR is
ignored, and pins automatically function as data
I/O pins.
Modes 2 and 3 (EXPE = 0)
The corresponding port 3 pins are output ports
when P3DDR bits are set to 1, and input ports
when cleared to 0.
