Verify that all D-Flash (and P-Flash) blocks are erased.
Verify that the D-Flash block is erased.
Erase all D-Flash (and P-Flash) blocks.
An erase of all Flash blocks is only possible when the FPLDIS, FPHDIS, and FPOPEN
bits in the FPROT register and the DPOPEN bit in the DFPROT register are set prior to
launching the command.
Erase a D-Flash (or P-Flash) block.
An erase of the full D-Flash block is only possible when DPOPEN bit in the DFPROT
register is set prior to launching the command.
Verify that all P-Flash (and D-Flash) blocks are erased.
Verify that a P-Flash block is erased.
Verify that a given number of words starting at the address provided are erased.
Read a dedicated 64 byte field in the nonvolatile information register in P-Flash block 0
that was previously programmed using the Program Once command.
Program a phrase in a P-Flash block.
Program a dedicated 64 byte field in the nonvolatile information register in P-Flash block
0 that is allowed to be programmed only once.
Erase all P-Flash (and D-Flash) blocks.
An erase of all Flash blocks is only possible when the FPLDIS, FPHDIS, and FPOPEN
bits in the FPROT register and the DPOPEN bit in the DFPROT register are set prior to
launching the command.
Erase a P-Flash (or D-Flash) block.
An erase of the full P-Flash block is only possible when FPLDIS, FPHDIS and FPOPEN
bits in the FPROT register are set prior to launching the command.
