LPC55 DMA and SPI memory maps

[kbetts]

I am writing an SPI DMA driver for the LPC55 as the NXP driver library doesn't quite do what I want. Is there a specification document available anywhere for the memory mapping of the SPI and DMA peripherals? I've pulled the structures out of the NXP drivers but I would like some more certainty that everything is as it should be, and to know whether the __I (input) __O (output) fields can be read from.

I have now found this information in the user manual. I was looking in the separate DMA document before

[ujwal_kumar_N_L]

can you please post the documents you used ?any other updates regarding your driver?

The User Manual can be found here:

The driver was developed for internal use by my company and is not available for distribution
