There are 5 programmable 8-bit I/O ports: Port A, Port B, Port C, Port D and Port E. These
ports all have multiple operating modes, depending on the configuration. Some of the basic
functions are providing input/output for the ZPLD, or can be used for standard I/O. Each port
pin is individually configurable, thus enabling a single 8-bit port to perform multiple func-
tions. The I/O ports occupy 256 bytes of memory space as defined by “CSIOP”. Refer to the
System Configuration section for I/O register address offset.
To set up the port configuration the user is required to:
1. Define I/O Port Chip Select (CSIOP) in the ABEL file.
2. Initialize certain port configuration registers in the user’s program and/or
3. Specify the configuration in the ZPSD4XX PSDsoft Software.
4. Unused input pins should be tied to V
CC
or GND.
The following is a description of the operating modes of the I/O ports. The functions of the
port registers are described in later sections.
Standard MCUI/O
The Standard MCU I/O Mode provides additional I/O capability to the microcontroller. In this
mode, the ports can perform standard I/O functions such as sensing or controlling various
external I/O devices. Operation options of this mode are as follows:
J
Configuration
1.Declare pins or signals which are used as I/O in the ABEL file.
2.Set the bit or bits in the Control Register to "1".
3.
As Output Port
– Write output data to Data Out Register
– Set Direction Register to output mode
4.
As Input Port
– Set Direction Register to input mode
– Read input from Data In Register
The port remains an output or input port as long as the Direction Register is not changed.
PLDI/O
The PLD I/O mode enables the port to be configured as an input to the ZPLD, or as an
output from the GPLD macrocell. The output can be tri-stated with a control signal defined
by a product term from the ZPLD. This mode is configured by the user in the ZPSD4XX
PSDsoft Software, and is enabled upon power up. For a detailed description, see the
section on the ZPLD.
J
Configuration
1.Declare pins or signals in the ABEL file (PSDsoft).
2.Write logic equations in the ABEL file.
3.PSD Compiler maps the PLD functions to the PSD.
