Sample Assembly Code to Erase and Reprogram the TMS320F240
PRELIMINARY
**************************************************************
** | Now that the data to be programmed is ready, the | ** |
** | programming algorithm is invoked. Note: Four parameters | ** |
** | must be initialized before calling the algorithm. | ** |

prg_error:
**********************************************************
** | If here, then an error occurred during programming. | ** |
** | In an actual application, the system takes some | ** |
** | action to indicate that service is required. | ** |

B | prg_error | ;Error while programming. |
prg_done:
**********************************************************
**If here, then flash has been successfully programmed. *
