In write operation, the HSMCI Mode Register (HSMCI_MR) is used to define the padding value when writing non-
multiple block size. If the bit PADV is 0, then 0x00 value is used when padding data, otherwise 0xFF is used.

If set, the bit DMAEN in the HSMCI_DMA register enables DMA transfer.

) shows how to write a single block with or without use of DMA facilities. Polling

or interrupt method can be used to wait for the end of write according to the contents of the Interrupt Mask Register
(HSMCI_IMR).
