Prior to downloading the new program, the write protection must be disabled. To do so,

press 4 (Disable the write protection) on the keyboard. The write protection is disabled

and a system reset is generated to reload the new option byte values. After resuming from

reset, the menu shown in Figure 3 is displayed if the key push-button is pressed.

Note:

In this application, the read protection is not supported, so the user has to verify that the

Flash memory is not read-protected.
