Register Mapping
Memory Control Register
Remap Control Register
The EBI is programmed using the registers listed in the table below. The Remap Control Regis-
ter (EBI_RCR) controls exit from Boot Mode (see
Memory Control Register (EBI_MCR) is used to program the number of active chip selects and
data read protocol. 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 different base address, even for unused chip selects.
