MVME162IG/D2 A-7
A
Memory Search Increment Size 00010000 This multi-CPU feature is 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 There will be no delay before the
Bug begins its search for a work
page.
Memory Search Delay Address FFFFD20F Default address is $FFFFD20F.
This is the MVME162 GCSR
GPCSR0 as accessed through
VMEbus A16 space and assumes
the MVME162 GRPAD (group
address) and BDAD (board
address within group) switches
are set to "on". This byte-wide
value is initialized to $FF by
MVME162 hardware after a
System or Power-on Reset. In a
multi-162 environment, where
the work pages of several Bugs
are to reside in the memory of
the primary (first) MVME162,
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 will be 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.
