b. Jumpers on headers J2, J6, J7, J8, J9, and J10 configure the
board as described in the instructions in Table 2-2.
3. Be sure that the two 256K x 16 177Bug EPROMs are installed
in proper sockets on the MVME177 module. Install the odd
label (such as B01) EPROM in socket XU1 (for Least
Significant Words), and install the even label (such as B02)
EPROM in XU2 (for Most Significant Words). Be sure that
physical chip orientation is correct, with flatted corner of each
EPROM aligned with corresponding portion of EPROM
socket on the MVME177 module.
4. This completes the MVME177 Module hardware preparation
procedures. Proceed to the next section to install the module
in the chassis. Refer to the setup procedure for your particular
chassis or system for details concerning the installation of the
MVME177.
Description
When this bit is a one (high), it instructs the debugger
to use local Static RAM for its work page (i.e.,
variables, stack, vector tables, etc.).
When this bit is a one (high), it instructs the debugger
to use the default setup/operation parameters in
ROM versus the user setup/operation parameters in
NVRAM. This is the same as depressing the RESET
and ABORT switches at the same time. This feature
can be used in the event the user setup is corrupted or
does not meet a sanity check. Refer to the ENV
command (Appendix B) for the ROM defaults.
Reserved for future use.
