Timeout counter. This specifies the number of SCK cycles multiplied by 4096, to wait before asserting the
DATA TIMEOUT IRQ. It is used during timeout is used for data transfer/write operations in SD/MMC modes.
Clock Pre-Divider. CLOCK_DIVIDE must be an even value from 2 to 254.
Serial Clock Rate. The value CLOCK_RATE is used to generate the transmit and receive bit rate of the
SSP. The bit rate is SSPCLK / (CLOCK_DIVIDE x (1+ CLOCK_RATE)). CLOCK_RATE is a value from 0
to 255.
