Each chip-select pin has an associated base address register. A base address is the
lowest address in the block of addresses enabled by a chip select. CSBARBT contains
the base address for selection of a boot memory device. Bit and field definitions for
CSBARBT and CSBAR[0:10] are the same, but reset block sizes differ. These regis-
ters may be read or written at any time.
This field sets the starting address of a particular chip-select’s address space. The ad-
dress compare logic uses only the most significant bits to match an address within a
block. The value of the base address must be an integer multiple of the block size.
Base address register diagrams show how base register bits correspond to address
lines.
This field determines the size of the block that is enabled by the chip-select.
