PCI Pass-Thru Configuration Register (PTCR)

This register controls the configuration for Pass-Thru

Regions 1-4:

Byte 0 Controls Pass-Thru Region 1

Byte 1 Controls Pass-Thru Region 2

Byte 2 Controls Pass-Thru Region 3

Byte 3 Controls Pass-Thru Region 4

IMPORTANT NOTE:

This register (PTCR) is physi-

cally the same as the Add-On Pass-Thru

Configuration Register (APTCR). It is intended that

either the PCI system or local Add-On interface will

write to this register, but not both. However, in the

event that both the PCI and Add-On must write to this

Also, Pass-Thru operation cannot be guaranteed if this

already in progress.
