Port Data Registers
The Port Data Registers, shown in Table
27
, are
used by the MCU to write data to or read data from
the ports. Table
27
shows the register name, the
ports having each register type, and MCU access
for each register type. The registers are described
below.
Data In
Port pins are connected directly to the Data In buff-
er. In MCU I/O input mode, the pin input is read
through the Data In buffer.
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 output enable product term is set to
‘
1.
’
The
contents of the register can also be read back by
the MCU.
Output Macrocells (OMC)
The CPLD Output Macrocells (OMC) occupy a lo-
cation in the microcontroller
’
s address space. The
microcontroller can read the output of the OMCs.
If the Mask Macrocell Register bits are not set,
writing to the Macrocell loads data to the Macrocell
flip flops. See the section entitled
PLD
’
S, page 34
.
Mask Macrocell Register
Each Mask Register bit corresponds to an OMC
flip flop. When the Mask Register bit is set to a
“
1
”
,
loading data into the OMC flip flop is blocked. The
default value is
“
0
”
or unblocked.
Input Macrocells (IMC)
The IMCs can be used to latch or store external in-
puts. The outputs of the IMCs are routed to the
PLD input bus, and can be read by the microcon-
troller.

to
the
PLD
