These bits are reserved and must be 0.
FSTAT—Flash Controller Status
00_0000 = Flash Controller locked.
00_0001 = First unlock command received.
00_0010 = Second unlock command received.
00_0011 = Flash Controller unlocked.
00_0100 = Flash Sector Protect Register selected.
00_1xxx = Program operation in progress.
01_0xxx = Page erase operation in progress.
10_0xxx = Mass erase operation in progress.
The Page Select (FPS) Register
programmed. Each Flash Page contains 512 bytes of Flash memory. During a Page Erase
operation, all Flash memory locations with the 7 most significant bits of the address given
by the PAGE field are erased to
The Page Select Register shares its Register File address with the Flash Sector Protect
Register. The Page Select Register cannot be accessed when the Flash Sector Protect
Register is enabled.
