25.4.2.10 Erase P-Flash Sector Command
The Erase P-Flash Sector operation will erase all addresses in a P-Flash sector.
Upon clearing CCIF to launch the Erase P-Flash Sector command, the Memory Controller will erase the
selected Flash sector and then verify that it is erased. The CCIF flag will be set after the Erase P-Flash
Sector operation has completed.
