Flash Write Protect Header (J16)
The firmware resident in Flash memory is originally loaded at the
factory, but the Flash contents can be reprogrammed if necessary.
To prevent inadvertent overwriting of the Flash memory, header
J16 provides write protection. With a jumper installed on J16, the
Flash memory can be written to via normal software routines.
When the jumper is removed (the factory configuration), Flash
memory cannot be written to.
