VSBC2 Requester Control

01000000

The bits in this register control

 

 

 

aspects of the local board’s

 

 

access of the VSB. Control and

 

 

status bits are available to

 

 

request control of the bus (and

 

 

determine when control has

 

 

been obtained), determine

 

 

whether the requester uses

 

 

"fairness" mode in arbitrating for

 

 

the bus, whether to release the

 

 

bus when done, and configure

 

 

the VSB requester arbitration ID

 

 

value. Definition of the register

 

 

contents can be found in the

 

 

MVME166 programmer’s

 

 

reference guide. Default =

 

 

01000000.

 

 

 

 

VSBC2 Timer Control Register

1000

The bits in this register control

 

 

various timers and their timeout

 

 

periods, for VSB accesses.

 

 

Definition of the register

 

 

contents can be found in the

 

 

MVME166 programmer’s

 

 

reference guide. Default = 1000.

 

 

 

VSBC2 Master Starting Address #1

00000000

Beginning address of an address

 

 

range for the local bus to VSB

 

 

map decoder #1. Only the upper

 

 

16 bits of this field are significant

 

 

(or used). Default = 00000000.

 

 

 

VSBC2 Master Ending Address #1

00000000

Ending address of an address

 

 

range for the local bus to VSB

 

 

map decoder #1. Only the upper

 

 

16 bits of this field are significant

 

 

(or used). Default = 00000000.

 

 

 

VSBC2 Master Address Offset #1

00000000

Address offset for the local bus

 

 

to VSB map decoder #1. The

 

 

upper 16 bits of this field will be

 

 

added to the upper 16 bits of the

 

 

local bus address received. This

 

 

sum is then the address driven

 

 

onto the VSB address lines.

 

 

Default = 00000000.
