Chapter 29 128 Kbyte Flash Module (S12XFTX128K1V1)

The sector erase operation will erase all addresses in a 1 Kbyte sector of Flash memory using an embedded

An example ﬂow to execute the sector erase operation is shown in

command write sequence is as follows:

If a Flash sector to be erased is in a protected area of the Flash block, 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 block 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 global address bits [9:0] and the

data written are ignored.
