Block device operations
Low Level SPI driver operations
The ECSD_LowLevel_WriteBlock writes a block of data to the SPI bus.
The pointer to the buffer with the data to write.
The number of bytes to write.
Returns one of the ECSD error codes (ECSD_STATUS_OK on success).
Called to write data to the SPI bus. Read data should be discarded. Note: You should never call this function directly. The API documentation is present to allow you to write your own low level driver optimized for your hardware.
