8.4
Port 4 is an 8-bit I/O port. Port 4 pins also function as external interrupt input, and TMR_0,
TMR_1, TMR_X, and TMR_Y input/output pins. Port 4 has the following registers.
• Port 4 data direction register (P4DDR)
• Port 4 data register (P4DR)
8.4.1
The individual bits of P4DDR specify input or output for the pins of port 4.
8.4.2
P4DR stores output data for the port 4 pins.

If port 4 pins are specified for use as the general I/O
port, the corresponding port 4 pins are output ports
when the P4DDR bits are set to 1, and input ports when
cleared to 0.
P4DR stores output data for the port 4 pins that are
used as the general output port.
If a port 4 read is performed while the P4DDR bits are
set to 1, the P4DR values are read. If a port 4 read is
performed while the P4DDR bits are cleared to 0, the
pin states are read.
