ColdFire Flash Module (CFM)
6.3.4.4
The CFMPROT specifies which Flash logical sectors are protected from program and erase operations.
The CFMPROT register is always readable and only writeable when LOCK = 0. To change which logical
sectors are protected on a temporary basis, write CFMPROT with a new value after the LOCK bit in
CFMCR has been cleared. To change the value of CFMPROT that will be loaded on reset, the protection
byte in the Flash configuration field must first be temporarily unprotected using the method just described
before reprogramming the protection bytes. Then the Flash Protection longword at offset 0x1D_0400 must
be written with the desired value.
The CFMPROT controls the protection of thirty-two 16-Kbyte Flash logical sectors in the 512-Kbyte
Flash array.
