I/O Ports
[Direction registers] PiD
The I/O ports have direction registers which determine the input/out-
put direction of each pin. Each bit in a direction register corresponds
to one pin, and each pin can be set to be input or output.
When “1” is set to the bit corresponding to a pin, this pin becomes an
output port. When “0” is set to the bit, the pin becomes an input port.
When data is read from a pin set to output, not the value of the pin
itself but the value of port latch is read. Pins set to input are floating,
and permit reading pin values.
If a pin set to input is written to, only the port latch is written to and the
pin remains floating.
[Pull-up control] PULL
By setting the pull-up control register (address 0016
16
), ports P0 and
P3 can exert pull-up control by program. However, pins set to output
are disconnected from this control and cannot exert pull-up control.
[Port P1P3 control] P1P3C
By setting the port P1P3 control register (address 0017
16
), a CMOS
input level or a TTL input level can be selected for ports P1
0
, P1
2,
P1
3,
and P3
7
by program.
Then, set “1” to each bit 6 of the port P3 direction register and port P3
register.
