DEMONSTRATION PROGRAMS
Communicating with the Z86129
Communications with the Z86129 is accomplished using
its serial communications interface. Through hardware
setup, this interface can be configured into either of two
serial protocols, I
2
C or SPI. The details of hardware setup
have been provided in the Serial Communications
Interface section and will not be dealt with here. It is
assumed that the user is familiar with the serial protocol
requirements.
Note:
In the following descriptions <ENTER> means
press the Enter key. An asterisk (*) signifies that
everything following the asterisk in that line is a comment.
I
2
C Operation
The Z86129 is configurable as an I
2
C slave device with the
seven-bit Slave Address=14h. Zilog can provide C
language programs which enable a PC to perform as the
I
2
C master device in an application. The PC
communicates with the Z86129 through its parallel port.
These programs are not intended as examples of how to
program the application but are only provided as a means
of illustrating the serial control process and the capability
of the Z86129.
The three programs available are titled IICO, SCRIPTI and
XDSCAP. These programs have been compiled and run
satisfactorily with the Z86129 in a test board. Compiled
versions are available on disk. Contact your local Zilog
sales office for further information on these programs.
IICO Program
This program will send one byte to the Z86129 without
checking the status of the READY bit. The program returns
the contents of the Serial Status (SS) Register after the
command has been entered. When the program is active
the screen will display:
IIC Command Byte >
The user may enter any valid one byte command such as
FBh (Reset) or 00h (NOP) and then hit the ENTER key.
The screen will then display the byte entered and the SS
register contents as follows:
IIC Byte = 00
IIC Status = 83h
The text above shows the NOP command was entered.
The SS register contents, 83h, indicates that the RDY,
FLD and LOCK bits are High indicating that the serial port
is ready for further input, that the input video signal was in
Field 1 at the time the status was read and that the part is
operating in video lock mode.
The IICO program is exited by entering a Control+C (^C)
character.
For example, entering the following single byte commands
would:
The commands that control most of the display capability
of the Z86129 are all one byte commands which can be
entered using the IICO program. These commands are
tabulated below for convenience.
