Erase Verify Block Command

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 128 Kbyte boundary in the P-Flash
memory space.
