The Erase Verify Block command allows the user to verify that an entire P-Flash or D-Flash block has been
erased. The FCCOB upper global address bits determine which block must be verified.

.
Upon clearing CCIF to launch the Erase Verify Block command, the Memory Controller will verify that
the selected P-Flash or D-Flash block is erased. The CCIF flag will set after the Erase Verify Block
operation has completed.

Erase Verify P-Flash Section Command
The Erase Verify P-Flash Section command will verify that a section of code in the P-Flash memory is
erased. The Erase Verify P-Flash Section command defines the starting point of the code to be verified and
the number of phrases. The section to be verified cannot cross a 256 Kbyte boundary in the P-Flash
memory space.
