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 location in the MCU’s
address space. The MCU can read the output of
the Output Macrocells (OMC). If the OMC Mask
Register bits are not set, writing to the macrocell
loads data to the macrocell flip-flops. See the sec-
tion entitled
PLDS, page 33
.
OMC Mask Register
Each OMC Mask Register bit corresponds to an
Output Macrocell (OMC) flip-flop. When the OMC
Mask Register bit is set to a 1, loading data into the
Output Macrocell (OMC) flip-flop is blocked. The
default value is 0 or unblocked.
