ENV - Set Environment
Use the ENV command to view and/or configure interactively all 177Bug
operational parameters that are kept in Non-Volatile RAM (NVRAM).
Refer to the Debugging Package for Motorola 68K CISC CPUs User’s
Manual for a description of the use of ENV. Additional information on
registers in the MVME177P that affect these parameters appears in your
MVME1X7P Single Board Computers Programmer’s Reference Guide.
Listed and described below are the parameters that you can configure
using ENV. The default values shown are those that were in effect when
this document was published.
Note
In the event of difficulty with the MVME177P, you may wish to
use env;d <CR> to restore the factory defaults as a
troubleshooting aid (see Appendix B).
