Function on P-Flash Memory
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 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
that is allowed to be programmed only once.
Erase all P-Flash (and EEPROM) 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 EEPROT register are set prior to
launching the command.
Erase a P-Flash (or EEPROM) 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 EEPROM)
blocks and verifying that all P-Flash (and EEPROM) 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).
