 * Note: The structure members are not strongly typed, as this file is included
 *       in application specific '.c' files. The mbed code structure does not
 *       allow inclusion of mbed driver files (e.g. mbed.h) into '.c' files.
 *       All the members are hence typecasted to mbed specific type during
 *       spi init and read/write operations.
