3.9 J301, J302 Flash Write Protection Configuration
Jumpers J301 and J302 are used to protect the contents of Flash banks
U300/U301 and U302/U303 from unauthorized or unintentional
erasure. By closing jumpers J301 and J302, the hardware mechanism
is activated for write protection of the individual Flash banks.
This feature is not supported by all the Flash devices that could be
populated on the module.
