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.
Load data for simultaneous multiple P-Flash block operations.
Program a phrase in a P-Flash block and any previously loaded phrases for any other P-
Flash block (see Load Data Field command).
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.
Erase a single 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.
Erase all bytes in a P-Flash sector.
Supports a method of releasing MCU security by erasing all P-Flash (and D-Flash) blocks
and verifying that all P-Flash (and D-Flash) blocks are erased.
Supports a method of releasing MCU security by verifying a set of security keys.
Specifies a user margin read level for all P-Flash blocks.
Specifies a field margin read level for all P-Flash blocks (special modes only).
