// A data buffer of max 8 16-bit words can be supplied to the program
// function.
// Each word is programmed until the whole buffer is programmed or a
// problem is found. However to program a buffer that has more than 8
// words, program function can be called in a loop to program 8 words for
// each loop iteration until the whole buffer is programmed.
//
// Remember that the main array flash programming must be aligned to
// 64-bit address boundaries and each 64 bit word may only be programmed
// once per write/erase cycle. Meaning the length of the data buffer
// (3rd parameter for Fapi_issueProgrammingCommand() function) passed
// to the program function can only be either 4 or 8.
//
// Program data in Flash using "AutoEccGeneration" option.
// When AutoEccGeneration option is used, Flash API calculates ECC for the
// given 64-bit data and programs it along with the 64-bit main array data.
// Note that any unprovided data with in a 64-bit data slice
// will be assumed as 1s for calculating ECC and will be programmed.
//
// Note that data buffer (Buffer) is aligned on 64-bit boundary for verify
// reasons.
//
// Monitor ECC address for the sector below while programming with
// AutoEcc mode.
//
// In this example, the number of bytes specified in the flash buffer
// are programmed in the flash sector below along with auto-generated
// ECC.
