Control Register – Write Only

 

ADDR

Plug-In LA+0x04

 

 

 

D15

A24/A32 Enable

1

= write a 1 to this bit to enable A24/A32 memory access

 

0

= to disable access

 

 

 

 

D14-D2

Reserved

Writes to these bits have no effect.

 

D1

Sysfail Inhibit

Write a 1 to this bit to prevent the module from asserting the

 

SYSFAIL* line.

 

 

 

 

D0

Reset

1

= write a 1 to this bit to force the module into a reset state

 

0

= write a 0 to release the reset state

 

 

 

 

 

Offset Register – Read and Write

 

ADDR

Plug-In LA+0x06

 

 

 

 

The value written to this 16-bit register, times 256, sets the base

 

 

 

address of the A24 memory space used by the module. The value

 

 

 

written to this 16-bit register, times 65,536, sets the base address

 

D15-D0

A24/A32 Memory

of the A32 memory space used by the module. A read from this

 

register reflects the previously written value. Because of the

 

Offset

 

 

required memory size, bits D4-D0 are disregarded on writes and

 

 

 

 

 

 

always read back as 0s. Upon receiving a hard reset, all bits in

 

 

 

this register are set to 0s. A soft reset does not effect the value in

 

 

 

this register. The resource manager sets this register.
