Table 4-2. Multiplexing, Interrupt Selection, and Base Address Registers (Continued)
Bit	Description

0	SDBE0 (Slave Disconnect Boundary Enable). Works in conjunction with the GX1 module’s PCI Control Function 2 Regis-
	ter (Index 41h), bit 1 (SDBE1). Sets boundaries for when the GX1 module is a PCI slave.
	SDBE[1:0]
	00: Read and Write disconnect on boundaries set by bits [3:2] of the GX1 module’s PCI Control Function 2 register (Index
	41h).
	01: Write disconnects on boundaries set by bits [3:2] of the GX1 module’s PCI Control Function 2 register. Read discon-
	nects on cache line boundary of 16 bytes.
	1x: Read and Write disconnect on cache line boundary of 16 bytes.
	This bit is reset to 1.
	All PCI bus masters (including SC2200’s on-chip PCI bus masters, e.g., the USB Controller) must be disabled while modify-
	ing this bit. When accessing this register while any PCI bus master is enabled, use read-modify-write to ensure these bit
	contents are unchanged.

Offset 38h	Interrupt Selection Register - INTSEL (R/W)	Reset Value: 00h

This register selects the IRQ signal of the combined WATCHDOG and High-Resolution timer interrupt. This interrupt is shareable with other interrupt sources.

7:4	Reserved. Write as read.

This register identifies the device. SC2200 = 04h.

Offset 3Dh			Revision Register - REV (RO)	Reset Value: xxh
This register identifies the device revision. See AMD Geode™ SC2200 Processor Specification Update document for value.

Offset 3Eh-3Fh			Configuration Base Address Register - CBA (RO)	Reset Value: xxh
This register sets the base address of the Configuration block.

15:6		Configuration Base Address. These bits are the high bits of the Configuration Base Address.

5:0		Configuration Base Address. These bits are the low bits of the Configuration Base Address. These bits are set to 0.
