bits of the PCI bus. The 8-bit byte-address for each of the following register loca-
tions is {AD[7:2], 00}. As a single-function device, Bt848 ignores bits AD[10:8].
ed in Bt848. User-definable features, BIST, Cache Line Size, and Expansion ROM
Base Address register are also not supported.
implemented:
Internal addressing of Bt848 registers occurs via AD[7:2] and the byte enable
CardBus CIS Pointer and Subsystem ID/VendorID registers are not implement-
The following types are used to specify how the Bt848 registers are
ROx: Read only with default value = x
RW:
RW*: Same as RW, but data read may not be same as data written.
RR:
Read/Write. All bits initialized to 0 at RST, unless otherwise
stated.
Same as RW, but writing a 1 resets corresponding bit location,
writing 0 has no effect.
