Removing all jumpers may temporarily disable the 
SRAM. Do not remove all jumpers from J14, except for 
storage.

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.
