256 KByte Flash Module (S12XFTMR256K1V1)

Upon clearing CCIF to launch the Erase Verify All Blocks command, the Memory Controller will verify

that the entire Flash memory space is erased. The CCIF ï¬ag will set after the Erase Verify All Blocks

operation has completed.

18.4.2.2 Erase Verify Block Command

The Erase Verify Block command allows the user to verify that an entire P-Flash or D-Flash block has been

erased. The FCCOB upper global address bits determine which block must be veriï¬ed.

Global address [22:16] of the

Flash block to be veriï¬ed.

Upon clearing CCIF to launch the Erase Verify Block command, the Memory Controller will verify that

the selected P-Flash or D-Flash block is erased. The CCIF ï¬ag will set after the Erase Verify Block

operation has completed.

18.4.2.3 Erase Verify P-Flash Section Command

The Erase Verify P-Flash Section command will verify that a section of code in the P-Flash memory is

erased. The Erase Verify P-Flash Section command defines the starting point of the code to be verified and

the number of phrases. The section to be verified cannot cross a 256 Kbyte boundary in the P-Flash

memory space.
