64 KByte Flash Module (S12FTMRC64K1V1)
If a Flash block is read during execution of an algorithm (CCIF = 0) on that same block, the read operation
will return invalid data. If the SFDIF or DFDIF flags were not previously set when the invalid read
operation occurred, both the SFDIF and DFDIF flags will be set.
If the ACCERR or FPVIOL bits are set in the FSTAT register, the user must clear these bits before starting
any command write sequence (see
17.4.5.1
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.
17.4.5.2
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.

A Flash word or phrase must be in the erased state before being
programmed. Cumulative programming of bits within a Flash word or
phrase is not allowed.
