(6) Do not apply 12 V to the FV
To prevent accidental programming or erasing due to microcontroller program runaway etc., apply
12 V to the V
is emulated by RAM. Overprogramming or overerasing due to program runaway can cause
memory cells to malfunction. Avoid system configurations in which 12 V is always applied to the
FV
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.
