The sector erase operation will erase all addresses in a 1024 byte sector of the Flash array using an
embedded algorithm.
An example flow to execute the sector erase operation is shown in
write sequence is as follows:
If a Flash sector to be erased is in a protected area of the Flash array, the PVIOL flag in the FSTAT register
will set and the sector erase command will not launch. Once the sector erase command has successfully
launched, the CCIF flag in the FSTAT register will set after the sector erase operation has completed unless
a new command write sequence has been buffered.

1. Write to a Flash array address to start the command write sequence for the sector erase command.
2. Write the sector erase command, 0x40, to the FCMD register.
3. Clear the CBEIF flag in the FSTAT register by writing a 1 to CBEIF to launch the sector erase
The Flash address written determines the sector to be erased while MCU address bits [9:0] and the
data written are ignored.
