I/O PORTS
Direction Registers
The I/O ports (ports P0, P1, P2, P4, P5, P6, P71–P77) have direc-
tion registers. Ports P16, P17, P4, P5, P6, and P71–P77 can be set
to input mode or output mode by each pin individually. P00–P07
and P10-P15 are respectively set to input mode or output mode in
a lump by bit 0 of the direction registers of ports P0 and P1 (see
Figure 13).
When “0” is set to the bit corresponding to a pin, that pin becomes
an input mode. When “1” is set to that bit, that pin becomes an
output mode.
If data is read from a port set to output mode, the value of the port
latch is read, not the value of the pin itself. A port set to input mode
is floating. If data is read from a port set to input mode, the value
of the pin itself is read. If a pin set to input mode is written to, only
the port latch is written to and the pin remains floating.
Port P3 Output Control Register
Bit 0 of the port P3 output control register (address 000716) en-
ables control of the output of ports P30–P37.
When the bit is set to “1”, the port output function is valid.
When resetting, bit 0 of the port P3 output control register is set to
“0” (the port output function is invalid) and pulled up.

Note: In pins set to segment output by segment output enable bits
0, 1 (bits 0, 1 of segment output enable register (address
3816)), this bit becomes invalid and pull-up resistor is not
connected.
