Notes: Do not apply a constant high level to the FWE pin. A high level should be applied to
the FWE pin only when programming or erasing flash memory. Also, while a high level
is applied to the FWE pin, the watchdog timer should be activated to prevent
overprogramming or overerasing due to program runaway, etc.
* For further information on FWE application and disconnection, see section 19.30,
