FSTAT—Flash controller status
000000 = Flash controller locked
000001 = First unlock command received (73H written)
000010 = Second unlock command received (8CH written)
000011 = Flash controller unlocked
000100 = Sector protect register selected
001xxx = Program operation in progress
010xxx = Page Erase operation in progress
100xxx = Mass Erase operation in progress
The Flash page select register shares address space with the Flash sector protect register.
Unless the Flash controller is locked and written with 5EH, any writes to this address will
target the Flash page select register.
The register selects one of the eight 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.
