9.4.4 Port Data Registers
The Port Data Registers, shown in Table 28, are used by the microcontroller to write data
to or read data from the ports. Table 28 shows the register name, the ports having each
register type, and microcontroller access for each register type. The registers are described
below.
9.4.4.1 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.
9.4.4.2 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 microcontroller.
9.4.4.3 Output Micro
Cells (OMCs)
The CPLD OMCs occupy a location in the microcontroller’s address space. The
microcontroller can read the output of the OMCs. If the Mask Micro
Cell Register bits are
not set, writing to the Micro
Cell loads data to the Micro
Cell flip flops. Refer to the PLD
section for more details.
9.4.4.4 Mask Micro
Cell 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.
9.4.4.5 Input Micro
Cells (IMCs)
The IMCs can be used to latch or store external inputs. The outputs of the IMCs
are routed to the PLD input bus, and can be read by the microcontroller. Refer to the PLD
section for a detailed description.
9.4.4.6 Enable Out
The Enable Out register can be read by the microcontroller. It contains the output enable
values for a given port. 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.
