Chip-Select Registers
10.4.1 Chip-Select Module Registers
The chip-select module is programmed through the chip select address registers
(CSAR0–CSAR7), chip select mask registers (CSMR0–CSMR7), and the chip select
control registers (CSCR0–CSCR7).
10.4.1.1 Chip-Select Address Registers (CSAR0–CSAR7)
Chip select address registers, Figure 10-2, specify the chip select base addresses.
Table 10-8 describes CSAR[BA].

Addresses not assigned to a register and undefined register bits are reserved for expansion. Write accesses to
these reserved address spaces and reserved register bits have no effect.
