Detailed Description

Manages communication with SD Card hardware memory module via SPI bus, using its vector table vtptr inside base structure, which points to functions that implement communication with SD Card hardware memory module via SPI bus. It also identifies and represents SD Card hardware memory module, by keeping all the relevant data about it. It is derived from physical_drive_t structure.
