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.
4.40.4.5.3
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.
Upon clearing CCIF to launch the Erase Verify P-Flash Section command, the Memory Controller will verify the selected section
of Flash memory is erased. The CCIF flag will set after the Erase Verify P-Flash Section operation has completed.
4.40.4.5.4
The Read Once command provides read access to a reserved 64 byte field (8 phrases) located in the nonvolatile information
register of P-Flash. The Read Once field is programmed using the Program Once command described in
Read Once command must not be executed from the Flash block containing the Program Once reserved field to avoid code
runaway.
