26.4.2.3 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.
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.
