26.4.2.10 Erase P-Flash Sector Command

The Erase P-Flash Sector operation will erase all addresses in a P-Flash sector.

Table 26-51. Erase P-Flash Sector Command FCCOB Requirements

CCOBIX[2:0]

000

001

FCCOB Parameters

0x0A

Global address [22:16] to identify

P-Flash block to be erased

Global address [15:0] anywhere within the sector to be erased.

Refer to Section 26.1.2.1 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 ï¬ag will be set after the Erase P-Flash

Sector operation has completed.

26.4.2.11 Unsecure Flash Command

The Unsecure Flash command will erase the entire P-Flash and D-Flash memory space and, if the erase is

successful, will release security.

Table 26-53. Unsecure Flash Command FCCOB Requirements

CCOBIX[2:0]

000

FCCOB Parameters

0x0B

Not required

Upon clearing CCIF to launch the Unsecure Flash command, the Memory Controller will erase the entire

P-Flash and D-Flash memory space and verify that it is erased. If the Memory Controller veriï¬es that the

entire Flash memory space was properly erased, security will be released. If the erase verify is not

successful, the Unsecure Flash operation sets MGSTAT1 and terminates without changing the security
