MSPM0G3507: SPI Controller to transmit 18bit SPI frame

RahulVK

Part Number: MSPM0G3507

Tool/software:

Hello,

I am planning to use the MSMP0G3507 to communicate with a peripheral that requires 18-bit SPI frame. I plan to accomplish this using PACKEN to transmit >16bit SPI frames without toggling CS signal after every 16bits. I noticed another forum post for MSPM0-L that concluded that PACKEN bit cannot be written to. Is this conclusion applicable to MSPM0G3507 as well?

Regards,

Rahul

Hi Rahul,

The same scenario will apply to MSPM0G3507.

Hi Luke,

Can you share a code example to make the SPI controller work manually toggling CS signal for packet lengths >16-bits? The code example from the MSPM0-L forum post is no longer available.

Rahul

Hi Rahul,

I'll contact the engineer to get the code example reuploaded and I'll send it in here once I have it.

Luke
