CardBus Socket Status and Control Base Address Bits:
-
The 32-bit Cardbus Base Address Register selects the starting address in memory space of the CardBus socket status and
control registers.
-
Actual register addresses are calculated by adding the MEMOFST of the register to this base address.
-
Bits [11:0] are read-only and are always 0, to indicate that the registers occupy 4KB of non prefetchable system memory space and
starts on a 4KB boundary.
