R00HIZ, R01HIZ: R00, R01 port high impedance control register (FF30HD0, D1)
Controls high impedance output of the output port.
When "1" is written: High impedance
When "0" is written: Data output
Reading: Valid
When using the BZ and XBZ outputs, fix the registers at "0". R01HIZ corresponds to the BZ output and
R00HIZ corresponds to the XBZ output.
At initial reset, these registers are set to "0".
R00, R01: R00, R01 output port data register (FF31H D0, D1)
Set the output data for the output ports.
When "1" is written: High level output
When "0" is written: Low level output
Reading: Valid
When using the BZ and XBZ outputs, fix the registers at "1". R01 corresponds to the BZ output and R00
corresponds to the XBZ output.
At initial reset, these registers are all set to "1".
