Port Data Registers
The Port Data Registers, shown in Table 21, are used by the microcontroller to write or
read data to or from the ports. Table 21 shows the register name, the ports having
each register type and microcontroller access for each register. The registers are described
below.

Table 21. Port Data Registers
Data In
Port pins are connected directly to the Data In buffer. In MCU I/O input mode, the pin input
is read through the Data In buffer. The MCU can always read the state of a Port pin using
this method, regardless of what is driving the pin.
Data Out Register
Stores output data written by the MCU in the MCU I/O output mode. The contents of the
Register are driven out to the pins if the Direction Register or the .oe product term is set to
“1”. The contents of the register can also be read back by the microcontroller.
Output Micro
Cell
The GPLD Output Micro
Cells occupy a location in the microcontroller’s address
space. The microcontroller can read the output of the Micro
Cells. Writing to the
Micro
Cell loads data to the Micro
Cell Flip-Flops. Refer to the PLD section for more
detail.
Input Micro
Cell
The Input Micro
Cells can be used to latch or store external inputs. The outputs of
the Input Micro
Cells are routed to the PLD input bus and also can be read by the
microcontroller. Refer to the PLD section for detail description.
Enable Out
The Enable Out buffer allows the microcontroller to read the outputs of the “OR” gate that
is the enable input to the port output driver. A “1” indicates the driver is in output mode, a “0”
indicates the driver is in tri-state and the pin is in input mode.
