Configure and Environment Commands

 asks the following series of questions to set up the VMEbus interface for the 

MVME162LX modules. You should have a working knowledge of the VMEchip2 as 
given in the MVME162LX Embedded Controller Programmer's Reference Guide in order to 
perform this conÞguration. Also included in this series are questions for setting ROM 
and Flash access time.
The slave address decoders are used to allow another VMEbus master to access a local 
resource of the MVME162LX. There are two slave address decoders set. They are set up 
as follows:

Slave Enable #1 [Y/N]

Y

Yes, set up and enable Slave Address 
Decoder #1. 

Slave Starting Address #1

00000000

Base address of the local resource that is 
accessible by the VMEbus. Default is the 
base of local memory, $0. 

Slave Ending Address #1

000FFFFF

Ending address of the local resource that 
is accessible by the VMEbus. Default is 
the end of calculated memory. 

Slave Address Translation 
Address #1

00000000

Register that allows the VMEbus address 
and the local address to be different. The 
value in this register is the base address of 
local resource that is associated with the 
starting and ending address selection 
from the previous questions. Default is 0. 

Slave Address Translation 
Select #1

00000000

Register that deÞnes which bits of the 
address are signiÞcant. A logical one ÔÔ1ÕÕ 
denotes signiÞcant address bits, a logical 
zero ÔÔ0ÕÕ non-signiÞcant bits. Default is 0. 

Slave Control #1

03FF

DeÞnes the access restriction for the 
address space deÞned with this slave 
address decoder. Default is $03FF. 

Slave Enable #2 [Y/N]

N

Do not set up and enable Slave Address 
Decoder #2. 

Slave Starting Address #2

00000000

Base address of the local resource that is 
accessible by the VMEbus. Default is 0.
