1.14 SDSPI Driver Synchronous - SDSPI Read Write

• The synchronous mode of the SDSPI driver is configured to use DMA and performs blocking read and write operations.
• This example uses the SDSPI driver in synchronous mode in an RTOS environment.
• A separate RTOS thread is created by the MHC to run the SDSPI task routine. This task routine checks for the SD-Card attach/detach status and initializes the SD-Card making it ready for the application to submit read and write requests.
• This application writes 10KB (10240 bytes) of data starting at the SD Card memory location 0x2000.
• The application then reads and verifies the written data.
