8067 Read Data
The Read Data bits are read/write bits that contain data
to be transferred out on the associated 8067 port in
response to a read request at that port.
8067 Write Data
The Write Data registers are read/write registers that
contain data which is transferred in on the associated
8067 port in response to a write request at that port.
Port Manual Enable
The microcontroller sets this bit to enable 8067 manual
mode for the associated port. When manual mode is
enabled the microcontroller has direct control over the
associated 8067 port using the MDATA
(0xFC25/0xFC2D) register, which contains output data,
