MSP432P401R: SPI driver (changed UART communication to SPI communication in project_zero)

Part Number: MSP432P401R
Other Parts Discussed in Thread: CC2650

Hello.

First, the hardware is as follows:
MSP-EXP432P401R (MSP432 LaunchPad)
LAUNCHXL-CC2650 (SimpleLink CC2650 BoosterPack)

We want to change the NPI in project_zero from UART to SPI and check the BLE operation.
1.The CC2650 side has been changed to support SPI. (Based on the answers in the E2E support forum)
2.I also changed the MSP432 side from UART to SPI. (Based on the answer in the E2E support forum)
3.I am debugging with CCS.
I'm having trouble in the middle of it. Please help me.
・When sending commands from the MSP432 side to the CC2650, the SPI driver (spi.c / SPIMSP432DMA.c) is used.
When the driver is used, the MRDY is output low and clocked, and data is output in the driver.
Is this the way it's supposed to be?
Also, is it possible to remove control of MRDY from the driver?

Best Regards.
