Port Data Registers
The Port Data Registers, shown in Table
97
, are
used by the MCU to write data to or read data from
the ports. Table
97
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 buffer. In MCU I/O Input Mode, the pin in-
put 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 con-
tents 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
PLDs, page 106
.
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 un-
blocked.
Input Macrocells (IMC).
The Input Macrocells
(IMC) can be used to latch or store external inputs.
The outputs of the Input Macrocells (IMC) are rout-
ed to the PLD input bus, and can be read by the
MCU. See
PLDs, page 106
.
Enable Out.
The Enable Out register can be read
by the MCU. It contains the output enable values
for a given port. A '1' indicates the driver is in out-
put mode. A '0' indicates the driver is in tri-state
and the pin is in input mode.
