15.6 Flash Memory Protection
There are three kinds of flash memory program/erase protection: hardware protection, software
protection, and error protection.
15.6.1 Hardware Protection
Hardware protection refers to a state in which programming/erasing of flash memory is forcibly
disabled or aborted. Hardware protection is reset by settings in the flash memory control register
(FLMCR) and erase block register (EBR). In the case of error protection, the P bit and E bit can be
set, but a transition is not made to program mode or erase mode. (See table 15.8.)
