Hi.
I know there are many threads mention this kind of questions. But I don't understand clearly from those. So I post this question. Please advise me.
I understand that we can access a 16-bit asynchronous device connected through EMIFA with following connection.
And I know that C-programming 16-bit (short pointer) access works fine with the configuration.
Does this configuration also work for 8-bit (char pointer) access? I assume that nEMA_WE_DQM[1:0] is dealing with this kind of access.
(DSP) (16-bit Async Device)
EMA_D[15:0] <---> DQ[15:0]
EMA_A[x:0] ----> A[(x+1):1]
EMA_BA[1] ----> A[0]
EMA_BA[0] (NC)
nEMA_WE_DQM[1:0] ----> BE[1:0]
Best regards,
Tsutomu Furuse
