About NOR Flash Write/Read in ASYNC mode (Non-ADMUX) at SEMC

[george]

Dear All,

Please tell me about Flash Write in ASYNC mode (Non-ADMUX) using SEMC.

The reference manual only gives examples for ADMUX mode, but how are the addresses assigned when using non-ADMUX mode?

Maybe SEMC_ADDR [8:0] is assigned to A [8:0]?

Please tell me one more thing.

What does the following note mean?

Maybe, Does this mean that there are few addresses available?

BR,

George

Hi George,

I have learnt that SEMC module implemented in i.MXRT1050 doesn't support non-ADMUX mode. So the customer need to use ADMUX or AADM mode only.
