21.5 Protection
There are three kinds of flash memory program/erase protection: hardware, software, and error
protection.
21.5.1 Hardware Protection
Programming and erasing of flash memory is forcibly disabled or suspended by hardware
protection. In this state, the downloading of an on-chip program and initialization are possible.
However, an activated program for programming or erasure cannot program or erase locations in a
user MAT, and the error in programming/erasing is reported in the parameter FPFR.
