SCSI Shadow Registers 4-123
Registers: 0xA8–0xAB
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.
