24.4.6.2 Erase Verify Block Command
The Erase Verify Block command allows the user to verify that an entire P-Flash or EEPROM block has
been erased. The FCCOB FlashBlockSelectionCode[1:0] 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 EEPROM block is erased. The CCIF flag will set after the Erase Verify Block
operation has completed.If the block is not erased, it means blank check failed, both MGSTAT bits will be
set.

MGSTAT1
None
Set if any errors have been encountered during the read² or if blank check failed.
MGSTAT0
Set if any non-correctable errors have been encountered during the read² or if
blank check failed.

24.4.6.3 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.
