5.19.4 Function Description
5.19.4.1 EBI Area and Address Hit
5.19.4.2 EBI Data Width Connection
EBI mapping address is located at 0x6000_0000 ~ 0x6001_FFFF and the total memory space is
128Kbyte. When system request address hit EBI’s memory space, the corresponding EBI chip
select signal is assert and EBI state machine operates.
For an 8-bit device (64Kbyte), EBI mapped this 64Kbyte device to 0x6000_0000 ~ 0x6000_FFFF
and 0x6001_0000 ~ 0x6001_FFFF simultaneously.
EBI support device whose address bus and data bus are multiplexed. For the external device with
separated address and data bus, the connection to device needs additional logic to latch the
address. In this case, pin ALE is connected to the latch device to latch the address value. Pin AD
is the input of the latch device, and the output of the latch device is connected to the address of
external device. For 16-bit device, the AD [15:0] shared by address and 16-bit data. For 8-bit
device, only AD [7:0] shared by address and 8-bit data, AD [15:8] is dedicated for address and
could be connected to 8-bit device directly.
