User Programming Mode Execution Procedure (Example)*: Figure 20.7 shows the execution
procedure for user programming mode when the on-board update routine is executed in RAM.

to FV
overerasing due to program runaway can cause memory cells to malfunction. While 12 V
is applied, the watchdog timer should be running and enabled to halt runaway program
execution, so that program runaway will not lead to overprogramming or overerasing. For
