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