3.5.3 Base Address Registers
A base address is the starting address for the block enabled by a given chip select. Block size deter-
mines the extent of the block above the base address. Each chip select has an associated base register
so that an efficient address map can be constructed for each application. If a chip-select base address
register is programmed with the same address as a microcontroller module or memory array, an access
to that address goes to the module or array and the chip-select signal is not asserted.
ADDR[23:11] — Base Address Field
This field sets the starting address of a particular address space. The address compare logic uses only
the most significant bits to match an address within a block. The value of the base address must be a
multiple of block size. Base address register diagrams show how base register bits correspond to ad-
dress lines.
BLKSZ — Block Size Field
This field determines the size of the block that must be enabled by the chip select. The following table
shows bit encoding for the base address registers block size field.
3.5.4 Option Registers
The option registers contain eight fields that determine timing of and conditions for assertion of chip-
select signals. For a chip-select signal to be asserted, all bits in the base address register must match
the corresponding internal upper address lines, and all conditions specified in the option register must
be satisfied. These conditions also apply to providing DSACK or autovector support.
