96 KByte Flash Module (S12FTMRG96K1V1)
25.4.6.3
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. If the section is not erased, it means blank check failed, both MGSTAT
bits will be set.
25.4.6.4
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
block containing the Program Once reserved field to avoid code runaway.
