EBI User Interface
1354D–ATARM–08/02
The EBI is programmed using the registers listed in the table below. The Remap Control
Register (EBI_RCR) controls exit from Boot Mode (See “Boot on NCS0” on page 26.)
The 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.
Base Address: 0xFFE00000 (Code Label EBI_BASE)
