Table 4-36. Erase flash sector command FCCOB requirements

CCOBIX[2:0] FCCOB parameters

000 0x0A Global address [23:16] to identify flash block to be erased

001

Global address [15:0] anywhere within the sector to be erased. Refer to Overview for the flash

sector size

Upon clearing FSTAT[CCIF] to launch the erase flash sector command, the memory

controller will erase the selected flash sector and then verify that it is erased. The

FSTAT[CCIF] flag will be set after the erase flash sector operation has completed.

Table 4-37. Erase flash sector command error handling

FSTAT

ACCERR

Set if CCOBIX[2:0] != 001 at command launch

Set if command not available in current mode (see Table 4-9)

Set if an invalid global address [23:16] is supplied.

(see Table 4-6)

Set if a misaligned longword address is supplied (global address [1:0] !=

00)

FPVIOL Set if the selected flash sector is protected

MGSTAT1 Set if any errors have been encountered during the verify operation

MGSTAT0

Set if any non-correctable errors have been encountered during the verify

operation

4.5.2.9.10 Unsecure flash command

The unsecure flash command will erase the entire flash and EEPROM memory space,

and if the erase is successful, will release security.

Table 4-38. Unsecure flash command FCCOB requirements

CCOBIX[2:0] FCCOB parameters

000 0x0B Not required

Upon clearing FSTAT[CCIF] to launch the unsecure flash command, the memory

controller will erase the entire flash and EEPROM memory space and verify that it is

erased. If the memory controller verifies that the entire flash and EEPROM memory

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

the unsecure flash operation sets FSTAT[MGSTAT1] and terminates without changing

the security state. During the execution of this command (FSTAT[CCIF] = 0), the user

must not write to any flash and EEPROM module register. The FSTAT[CCIF] flag is set

after the unsecure flash operation has completed.
