Chapter 9 512 KByte Flash Module (S12XFTM512K3V1)
9.4.2.1
The Erase Verify All Blocks command will verify that all P-Flash and D-Flash blocks have been erased.
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 flag will set after the Erase Verify All Blocks
operation has completed.
9.4.2.2
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 verified.
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 flag will set after the Erase Verify Block
operation has completed.
