For a peripheral I need 16 bit Multiplex addressing is this possible in SEMC NAND mode?
Page 1485 of the ref. RT1064 manual tells the pin layout.
How do I setup this in software?
This is the sequence. bus speed is max 20Mhz.
ALEHI is not needed. So only ALE.

Thanks for the reply.
The problem is, it is not in the datasheet or not very clear in the datasheet.
NXP has to add this info in the datasheet or make it more clear how it is done!
I also asked the NXP field application engineer if he is able to provide the info needed.
Hello Sabina,
Can you please provide information how to configure the: Address Latch Enable (ALE) signal in this tool I cannot find it/ understand it.
Thanks.,
Hope you are well. For the SEMC NAND Control block I recommend to check table 9-17 of the reference manual. Here you will find the parameters to configure for your specific nand flash.
These parameters can be configured using the NAND Control Registers.
How these parameters are filled, depends on the information from the datasheet of the part you are using. For example I checked the parameters for a random nand flash.
The config tool allows you to configure the general configurations of the SEMC. You may configure the NAND control register using the DCD tool.
Hope this helps!

Hello Ernst,
Hope you are doing well.
The 16 bit ADMUX is possible in NOR and SRAM. You may find the details of the pin layout in the table located in section 25. 5. 3 in the page you make reference to.
Best Regards,
Sabina

Hello Sabina,
I already found that. I like a bit more detail. How do setup the software for this to work?
Thanks,
Ernst
Hello Ernst,
Hope you are doing well.
If you would like to get started on example software. I'd recommend to download the latest SDK and import the corresponding examples for SEMC.
In addition you may use the peripheral config tool, to configure specific characteristics of the SEMC module to fit your application. This tool can generate the adequate C code, for faster startup process in your development.
Best Regards,
Sabina
