EBI User Interface
The EBI is programmed using the registers listed in the
table below. The Remap Control Register (EBI_RCR) con-
trols exit from boot mode (see "Boot" on page 14). The
Memory Control Register (EBI_MCR) is used to program
the number of active chip selects and data read protocol.
Base Address: 0xFFE00000

Memory Control Register
Eight chip select registers (EBI_CSR0 to EBI_CSR7) are
used to program the parameters for the individual external
memories. Each EBI_CSR must be programmed with a dif-
ferent base address, even for unused chip selects.
