/// \unit
///
/// !!!Purpose
///
/// The AMD %norflash Low-level driver code implement procedures to program
/// basic operations described AMD-specified command set flash devices.
/// The various commands recognized by the devices are listed in the Commands
/// Tables provided in the corresponding AMD command set compatible flash
/// datasheets. All operation functions are blocked, they wait for the
/// completion of an operation by polling the status register.
///
/// !!!Usage
/// -# Flash program using AMD_Write_Data().
/// - The Program command is used to modify the data stored at the
/// specified device address. Programming can only change bits
/// from ¡®1¡¯ to ¡®0¡¯. It may be necessary to erase the block before
/// programming to addresses within it. Programming modifies a single
/// Word at a time using static function amd_Program(). Programming
/// larger amounts of data must be done in one Word at a time by
/// giving a Program command, waiting for the command to complete,
/// giving the next Program command and so on.
/// -# erase a block within the flash using AMD_EraseSector().
/// - Flash erase is performed on a block basis. An entire block is
/// erased each time an erase command sequence is given.
/// -# erase whole blocks within the flash using AMD_EraseChip().
/// -# AMD_Reset() function can be issued, between Bus Write cycles
/// before the start of a program or erase operation, to return the
/// device to read mode.
/// -# AMD_ReadDeviceID() is used to retrieve information
/// about the Flash Device type.
/// -# AMD_ReadManufactoryId() is used to retrieve information
/// about the Flash Device Manufactory ID.
