ColdFire Flash Module (CFM)
6.3.4.8
The CFMCMD is the register to which Flash program, erase, and verify commands are written.
CFMCMD is readable and writable in all modes. Writes to bit 7 have no effect and reads return 0.
6.4
The CFM registers, subject to the restrictions previously noted, can generally be read and written (see
Section 6.3.4, “Register

Erase Verified Flag. The BLANK flag indicates that the erase verify command
(RDARY1) has checked the two interleaved Flash physical blocks and found them
to be blank. Clear BLANK by writing it to 1. Writing a 0 has no effect.
1 Flash physical blocks verify as erased.
0 If an erase verify command has been requested, and the CCIF flag is set, then
Reserved, should be cleared.
