The SCP/DCP-122 provides a jumper to allow programming of the application Flash.
“Application Flash” means all Flash areas except the PABS Flash. The application Flash is in
the range 0xFC00 0000 to 0xFDFF FFFF.
For normal operation, remove jumper E3-E4 to write-protect the application Flash. To
program the application Flash, install the E3-E4 jumper.
