10.11 EBI User Interface
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 “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 param-
eters 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
)
Notes: 1. 8-bit boot (if BMS is detected high)
2. 16-bit boot (if BMS is detected low)
