MSP430F4371: How to use external parallel memory with a MSP430?

Hello,

MSP430 does not have any examples for parallel interface for this part. You will have to bit bang it by writing to the GPIO registers. I would recommend utilizing the same GPIO port for all of the lines so you only have to write to one port per data send/receive. 

From the schematic, that isn't very parallel. I see an 8 bit data connection plus a bunch of control signals to control a NAND flash. So the address and data would appear to share that data bus and have to be shifted in. A little faster than a 1 bit wide bus but not quite what I think of when I think of parallel memory.

If the serial memory interface is causing a noise problem. you might have a problem with your design that makes it sensitive to noise.

Hello Jace H. and David Schultz

Thanks for the tips, I change to FR5994 because I already have the dev board and done some code.

The port 3 is complete so I can do a prototype using that port for the I/O Data lines.

Do you have any advice for the P3DIR and P3SELs usage?

It's also why I was looking for the code because of the switch of the port (input/output) during program execution

I need fast reading / writing to the memory with the lowest frequency (to lower the noise) it’s why I go to parallel memory
