Apply the reset signal while SWE is low to reset the flash memory during its operation: The
reset signal is applied at least 100 μs after the SWE bit has been cleard.
Comply with power-on procedure designated by the programmer maker: When executing an
on-board writing with a programmer, incorrect programming or erasing may occur unless the
power-on procedure designated by the programmer makers is applied.
