A.3.6 Manufacturing Test Register±ManTest @ 0x04 (DIO)

This 16-bit register is used for manufacturing test. The options controlled by this register only take effect while the MTEST bit in the NetConfig register is set. The functions controlled by this register are for Texas Instruments manufacturing test only.

A.3.7 Default PCI Parameter Registers±@ 0x08±0x0C (DIO)

These eight read-only bytes indicate the default contents of the autoloadable PCI configuration registers. These default values are loaded into the respec- tive PCI configuration registers if autoload fails (bad checksum).
