5 PERIPHERAL CIRCUITS AND THEIR OPERATION (I/O Ports)
5.6.3 I/O control registers and I/O mode
I/O ports P00–P07 and P10–P17 are set either to
input or output modes by writing data to the I/O
control registers IOC00–IOC07 and IOC10–IOC17
which correspond to each bit.
To set an I/O port to input mode, write "0" to the I/
O control register.
An I/O port which is set to input mode will shift to a
high impedance state and functions as an input port.
Readout in input mode consists simply of a direct
readout of the input terminal state: the data being "1"
when the input terminal is at HIGH (VDD) level and
"0" when it is at LOW (VSS) level.
When the "With resistor" option is selected using
the mask option, the resistor is pulled up onto the
port terminal in input mode.
Even in input mode, data can be written to the data
registers without affecting the terminal state.
To set an I/O port to output mode, write "1" to the
I/O control register. An I/O port which is set to
output mode functions as an output port.
When port output data is "1", a HIGH (VDD) level is
output and when it is "0", a LOW (VSS) level is
output. Readout in output mode consists of the
contents of the data register.
At initial reset, I/O control registers are set to "0"
(I/O ports are set to input mode).
5.6.4 I/O memory for I/O ports
Table 5.6.4.1 shows the I/O port control bits.
