ENV Parameter and Options

Default

Meaning of Default

 

 

 

 

 

 

 

VMEC2 GCSR Group Base Address

CC

Specifies the group address

 

 

 

($FFFFXX00) in Short I/O for

 

 

this board. Default = $CC.

 

 

 

VMEC2 GCSR Board Base Address

00

Specifies the base address

 

 

($FFFFCCXX) in Short I/O for

 

 

this board. Default = $00.

 

 

 

VMEbus Global Time Out Code

01

This controls the VMEbus

 

 

timeout when systems

 

 

controller. Default $01 = 64 μs.

 

 

 

Local Bus Time Out Code

00

This controls the local bus

 

 

timeout. Default $00 = 8 μs.

 

 

 

VMEbus Access Time Out Code

02

This controls the local bus to

 

 

VMEbus access timeout. Default

 

 

$02 = 32 ms.

 

 

 

 

The special 166Bug parameters that can be configured using ENV are as follows.

 

 

 

 

VSBC2 Installed [Y/N]

Y

This is set depending on the

 

 

existence of a VSBchip2 on the

 

 

board. It can be overridden with

 

 

this ENV option.

 

 

 

VSBC2 Interrupt Vector Base

0E

Vector passed back to the VSB

 

 

master during the Status/ID

 

 

transfer phase of an interrupt-

 

 

acknowledge cycle, if the

 

 

VSBchip2 wins interrupt

 

 

arbitration. Default = 0E.

 

 

 

VSBC2 Local Interrupt Vector Base

00

The value here is part of the

 

 

interrupt vector supplied on the

 

 

local bus during an interrupt

 

 

acknowledge cycle. The lower 4

 

 

bits are reserved (and are read-

 

 

only, as zeroes). Bits 4 through 7

 

 

are programmable. Default = 00.

 

 

 

VSBC2 Slave Starting Address #1

00000000

Beginning address of an address

 

 

range for the first VSB to local

 

 

bus map decoder. Only the

 

 

upper 16 bits of this field are

 

 

significant (or used). Default =

 

 

00000000.

 

 

 

 

VSBC2 Slave Ending Address #1

00000000

Ending address of an address

 

 

range for the first VSB to local

 

 

bus map decoder. Only the

 

 

upper 16 bits of this field are

 

 

significant (or used). Default =

 

 

00000000.
