CCOBIX[2:0]
000
001
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.

001
FCCOB Parameters
0x0A
Global address [17:16] to identify
P-Flash block to be erased
Global address [15:0] anywhere within the sector to be erased.
Refer to Section 28.1.2.1 for the P-Flash sector size.
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.
