Example #1

//! This function initializes the memory for a write operation
//! from ram buffer to SD/MMC (1 sector)
//!
//!         DATA FLOW is: RAM => SD/MMC
//!
//! (sector = 512B)
//! @param addr         Sector address to write
//! @param ram          Ram buffer pointer
//!
//! @return                Ctrl_status
//!   It is ready      ->    CTRL_GOOD
//!   An error occurs  ->    CTRL_FAIL
//!
