Configure and Environment Commands

Memory Search Delay 
Address

FFFFD20F

Default address is $FFFFD20F. This is the 
MVME162LX GCSR (global 
control/status register) GPCSR0 as 
accessed through VMEbus A16 space. It is 
assumed that the MVME162LX GRPAD 
(group address) and BDAD (board 
address within group) switches are set to 
ÔÔonÕÕ. This byte-wide value is initialized 
to $FF by MVME162LX hardware after a 
System or Power-on Reset. In a multi-162 
environment, where the work pages of 
several Bugs will reside in the memory of 
the primary (Þrst) MVME162LX, 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.
