There are two modes for flash memory program/erase protection: hardware protection and
software protection. These two protection modes are described below.
Software Protection: With software protection, setting the P or E bit in the flash memory control
register (FLMCR) does not cause a transition to program mode or erase mode.
Details of software protection are given below.

Protect Modes
Description
Programming and erase protection can be
set for individual blocks by settings in the
erase block registers (EBR1 and EBR2).
Setting EBR1 to H'F0 and EBR2 to H'00
places all blocks in the program/erase-
protected state.
