CC2640R2F: What is the rate of SPI in coprocessor development and how should the DMA of coprocessor SPI be used?

Hi team,

Here's the request from the customer:

When the customer is using Sensor Controller Studio, the rate supported by SPI and the DMA usage of coprocessor SPI are not found in the development manual.

1. Is it 1.1MHz to use master-slave mode after CSC is configured here (can set a specified rate, such as 512K)? Is the maximum rate of master-slave mode 1.1MHz?
2. Customer wants to use the DMA function of the coprocessor SPI and he has seen the FIFO of the ADC in the example file of the ADC, but not in the SPI. How to use the DMA function of the SPI with the coprocessor?

Could you help check this case? Thanks.

Best Regards,
