Memory Search Increment Size
00010000
Multi-CPU feature used to offset the location
of the Bug work page. This must be a multiple
of the debugger work page, modulo $10000
(64KB). Typically, Memory Search Increment
Size is the product of CPU number and size of
the Bug work page. Example: first CPU $0 (0 x
$10000), second CPU $10000 (1 x $10000),
etc.
Memory Search Delay Enable
[Y/N]
N
No delay before the Bug begins its search for a
work page.
Memory Search Delay Address
FFFFD20F
Default address is $FFFFD20F. This is the
MVME177P GCSR GPCSR0 as accessed
through VMEbus A16 space; it assumes the
MVME177P GRPAD (group address) and
BDAD (board address within group) switches
are set to "on". This byte-wide value is
initialized to $FF by MVME177P hardware
after a System or Power-On reset. In a multi-
177P environment, where the work pages of
several Bugs reside in the memory of the
primary (first) MVME177P, 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 definition of these values)
before attempting to locate their work page in
the memory of the primary CPU.
Memory Size Enable [Y/N]
Y
Memory is sized for Self-Test diagnostics.
Memory Size Starting Address
00000000
Default Starting Address is $0.
Memory Size Ending Address
00100000
Default Ending Address is the calculated size
of local memory.
