CAUTION
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.
9.4.2.1
Erase Verify All Blocks Command
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 ag will set after the Erase Verify All Blocks
operation has completed.
9.4.2.2
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 veried.
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 ag will set after the Erase Verify Block
operation has completed.
