Unless the Flash controller is unlocked and written with 5EH, writes to this address target
the Flash Page Select Register.
The register is used to select one of the 8 available Flash memory pages to be programmed
or erased. Each Flash Page contains 512 bytes of Flash memory. During a Page Erase
operation, all Flash memory having addresses with the most significant 7-bits given by
FPS[6:0] are chosen for program/erase operation.
INFO_EN—Information Area Enable
0 = Information Area us not selected
1 = Information Area is selected. The Information Area is mapped into the Program Mem-
