Section
Read Once
Program P-Flash
Program Once
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 EPDIS and EPOPEN bits in the EPROT register are set prior
to launching the command.
0x08
Erase All Blocks
0x09
Erase a single P-Flash block.
Erase P-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.
