Contains five 2-bit fields (CSPA1[4:0]) that determine the functions of corresponding
chip-select pins. CSPAR1[15:10] are not used. These bits always read zero; write has
no effect. The CSPAR1 pin assignments table shows alternate functions that can be
enabled by data bus mode selection during reset.
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 bootstrap peripheral memory device. Bit and field
definition for CSBARBT and CSBAR[0:10] are the same, but reset block sizes differ.
This field sets the starting address of a particular address space.
