CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (I/O Ports)
The output specification during output mode (IOC = "1") of
the I/O port can be set with the mask option for either
complementary output or Pch open drain output. This
setting can be performed for each bit of the I/O port. How-
ever, when Pch open drain output has been selected, voltage
in excess of the supply voltage must not be applied to the
port.
Table 4.5.1 lists the I/O port control bits and their ad-
dresses.

I/O port data (0F4H)
I/O port data can be read and output data can be written
through the port.
When writing data
When "1" is written:
High level
When "0" is written:
Low level
When an I/O port is set to the output mode, the written
data is output from the I/O port pin unchanged. When
"1" is written as the port data, the port pin goes high
(VDD), and when "0" is written, the level goes low (VSS).
Port data can also be written in the input mode.
