Table 98. Port Data Registers
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 oftheRegister are driven outto the pins ifthe
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
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”, on page 108.
Output
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
(IMC) can be used to latchor store external inputs.
The outputs of theInput Macrocells (IMC) arerout-
ed to the PLD input bus, and can be read by the
MCU. See the section entitled “PLDs”, on page
108.
Enable Out.
The Enable Out register can beread
by the MCU. It contains the output enable values
for a given port. A1 indicates the driver is in output
mode. A0 indicates thedriver isin tri-state and the
pin is in input mode.
