If the EEPROM memory to be erased contains any protected area, the PVIOL flag in the ESTAT register will set and the mass erase command will not launch. Once the mass erase command has successfully launched, the CCIF flag in the ESTAT register will set after the mass erase operation has completed unless a new command write sequence has been buffered.

4.1.3.5 Sector Erase Abort Command

The sector erase abort operation will terminate the active sector erase or sector modify operation so that other sectors in an EEPROM block are available for read and program operations without waiting for the sector erase or sector modify operation to complete.

An example flow to execute the sector erase abort operation is shown in Figure 4-6. The sector erase abort command write sequence is as follows:
