Script Files
Script files can be generated to perform all of the setup and
control functions required to use the part in an application.
The script files shown below are examples of such files
used to setup the Z86129 for different operating
conditions. Some of the files contain only a single
command while others include several commands. The
user should refer to the Command and Registers section
for details. Although the following examples are organized
according to a particular register, some of the files contain
information for several registers.
