ENV Parameter and Options
Default
Meaning of Default
Memory Search Delay Address
FFFFD00F
The default address is
$FFFFD00F. This is the
MVME197LE GCSR
(global control and
status register) GPCSR5
as accessed through the
VMEbus A16 space and
assumes that the
MVME197LE GRPAD
(group address) and
BDAD (board address
within group) switches
are set to “ON”. This
byte-wide value is
initialized to $FF by the
MVME197LE hardware
after a System or Poweron Reset. In a multi-197
environment, where the
work pages of several
Bugs are to reside in the
memory of the primary
(first) MVME197LE, 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 the Debugger
General Information
chapter of this guide for
the definition of these
values) before
attempting to locate
their work page in the
memory of the primary
CPU.
