I/O PORTS
The I/O ports have direction registers which determine the
input/output direction of each individual pin. Each bit in a
direction register corresponds to one pin, and each pin can be set
to be input port or output port.
When “0” is written to the bit corresponding to a pin, that pin
becomes an input pin. When “1” is written to that bit, that pin
becomes an output pin.
If data is read from a pin which is set to output, the value of the
port output latch is read, not the value of the pin itself. Pins set to
input are floating. If a pin set to input is written to, only the port
output latch is written to and the pin remains floating.
By setting the port P0, P1, P2 pull-up control register (address
001216), the port P3 pull-up control register (address 001316), or
the port P4 pull-up control register (address 001416), ports can
control pull-up with a program. However, the contents of these
registers do not affect ports programmed as the output ports.
NOTES:
1. When bits 5 to 7 of Ports P3 and P4 are read out, the contents are undefined.
