Default
Meaning of Default
FFFFCE0F Default address is $FFFFCE0F. This is
the MVME177 GCSR GPCSR0 as
accessed through VMEbus A16 space
and assumes the MVME177 GRPAD
(group address) and BDAD (board
address within group) switches are set
to "on". This byte-wide value is
initialized to $FF by MVME177
hardware after a System or Power-on
Reset. In a multi-MVME177
environment, where the work pages of
several Bugs are to reside in the
memory of the primary (Þrst)
MVME177, the non-primary CPUs will
wait for the data at the Memory Search
Delay Address to be set to $00, $01, or
$02 (refer to the Memory Requirements
section in Chapter 3 for the deÞnition of
these values) before attempting to
locate their work page in the memory of
the primary CPU.
Y
Memory will be sized for Self Test
diagnostics.
00000000 Default Starting Address is $0.
02000000 Default Ending Address is the
calculated size of local memory.
00000000 Beginning address of Local Memory. It
must be a multiple of the Local Memory
board size, starting with 0. The Bug will
set up hardware address decoders so
that Local Memory resides as one
contiguous block at this address.
Default is $0.
02000000
You are prompted twice, once for each
00000000
possible MVME177 memory board.
Default is the calculated size of the
memory board.
