Shadowed SCRIPT Fetch Selector (SFS)
Read/Write

SFS

Shadowed SCRIPT Fetch Selector

[31:0]

When the PCI Configuration Info Enable bit in the

Chip Test Two (CTEST2)

register is set, the

SCRIPT Fetch Selector register is placed in shadow
mode. In this mode, bits [23:16] of this register return the
PCI

Revision ID (RID)

register value and bits [15:0] return

the PCI

Device ID

register value when read. Writes to the

SCRIPT Fetch Selector (SFS)

register have no effect.

Clearing the PCI Configuration Info Enable bit causes the
SFS register to return to normal operation.
