signals are visible.
The EBI unit between the NAND flash interface and the MPMC contains an arbiter that
determines which interface is muxed to the outside world. Both NAND flash and
SDRAM/SRAM initiate a request to the EBI unit. This request is granted using round-robin
arbitration (see
As is shown in
different supply domain than the LCD interface. The EBI control and address signals are
muxed with the LCD interface signals and are part of supply domain SUP8. The
SDRAM/SRAM data lines are shared with the NAND flash through the EBI and are part of
supply domain SUP4. Therefore the following rules apply for connecting memories:

for SDRAM/SRAM/bus-based LCD and NAND flash must be the same.The dedicated
LCD interface is not available in the MPMC mode.
