FCCOB Parameters
0x09
Global address [17:16] to
identify Flash block
Global address [15:0] in Flash block to be erased
Upon clearing CCIF to launch the Erase Flash Block command, the Memory Controller will erase the
selected Flash block and verify that it is erased. The CCIF flag will set after the Erase Flash Block
operation has completed.
