16.4.5.9 Erase P-Flash Sector Command
The Erase P-Flash Sector operation will erase all addresses in a P-Flash sector.
Table 16-47. Erase P-Flash Sector Command FCCOB Requirements
CCOBIX[2:0]
000
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 16.1.2.1 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.
Table 16-48. Erase P-Flash Sector Command Error Handling
Register
Error Bit
Error Condition
Set if CCOBIX[2:0] != 001 at command launch
ACCERR
Set if command not available in current mode (see Table 16-27)
Set if an invalid global address [17:16] is supplied¹
FSTAT
FPVIOL
Set if a misaligned phrase address is supplied (global address [2:0] != 000)
Set if the selected P-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
1 _{As defined by the memory map for FTMRC64K1.}
16.4.5.10 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 16-49. 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 verifies 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
state. During the execution of this command (CCIF=0) the user must not write to any Flash module
register. The CCIF flag is set after the Unsecure Flash operation has completed.
