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.

28.4.2.1 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 ﬂag will set after the Erase Verify All Blocks

operation has completed.

28.4.2.2 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 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.
