CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (I/O Ports)
IOC0, IOC1: I/O control registers (2EEHD0, 2FEHD0)
The input and output modes of the I/O ports can be set with these registers.
When "1" is written : Output mode
When "0" is written : Input mode
Read-out : Valid
The input and output modes of the I/O ports are set in units of four bits. IOC0 sets the mode for P00–P03,
and IOC1 sets the mode for P10–P13.
Writing "1" to the I/O control register makes the corresponding I/O port enter the output mode, and
writing "0" induces the input mode.
At initial reset, these two registers are set to "0", so the I/O ports are in the input mode.
4.6.5 Programming notes
(1) When input data are changed from high to low by built-in pull-down resistance, the fall of the
waveform is delayed on account of the time constant of the pull-down resistance and input gate
capacitance. Consequently, if data is read out while the CPU is running in the OSC3 oscillation circuit,
data must be read out continuously for about 500 sec.
(2) When the I/O port is set to the output mode and the data register has been read, the terminal data
instead of the register data can be read out. Because of this, if a low-impedance load is connected and
read-out performed, the value of the register and the read-out result may differ.
