ADDR[23:11] — Base Address Field
This field sets the starting address of a particular chip-select’s address space. The address compare
logic uses only the most significant bits to match an address within a block. The value of the base ad-
dress must be a multiple of the block size. The base address register diagrams above show how register
bits correspond to CPU address lines.
BLKSZ[2:0] — Block Size Field
This field determines the size of the block that must be enabled by the chip-select. Table 23 shows bit
encoding for the base address registers block size field.
3.6.4 Option Registers
The option registers contain eight fields that determine timing of and conditions for assertion of chip-
select signals. To assert a chip-select signal, and to provide DSACK or autovector support, other con-
straints set by fields in the option register and in the base address register must also be satisfied.
