    Single Word Program Operation
    Software Functions and Sample Code
    Note
    Base = Base Address.
    The following is a C source code example of using the single word program function. See the
    Spansion Low
    Level Driver User’s Guide
    (available on
    www.spansion.com
    ) for general information on Spansion Flash
    memory software development guidelines.
    /* Example: Program Command */
    *((UINT16 *)base_addr + 0x555) = 0x00AA; /* write unlock cycle 1 */
    *((UINT16 *)base_addr + 0x2AA) = 0x0055; /* write unlock cycle 2 */
    *((UINT16 *)base_addr + 0x555) = 0x00A0; /* write program setup command */
    *((UINT16 *)pa) = data; /* write data to be programmed */
    /* Poll for program completion */
