ENV - Set Environment
Use the ENV command to view and/or configure interactively all PPCBug operational
parameters that are kept in Non-Volatile RAM (NVRAM).
Refer to the PPCBug Firmware Package User's Manual for a description of the use of ENV.
Additional information on registers in the Universe ASIC that affect these parameters is
contained in your MVME5100 Programmer's Reference Guide, listed in
Documentation.
Listed and described below are the parameters that you can configure using ENV. The default
values shown were those in effect when this publication went to print.
