807

 summarizes the valid EEPROM commands along with the effects of the commands on the

EEPROM block.

0x02

Erase Verify Block

Verify that a P-Flash block is erased.

0x03

Erase Verify

P-Flash Section

Verify that a given number of words starting at the address provided are erased.

0x04

Read Once

Read a dedicated 64 byte field in the nonvolatile information register in P-Flash block that
was previously programmed using the Program Once command.

0x06

Program P-Flash

Program a phrase in a P-Flash block.

0x07

Program Once

Program a dedicated 64 byte field in the nonvolatile information register in P-Flash block
that is allowed to be programmed only once.

0x08

Erase All Blocks

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.

0x09

Erase Flash Block

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.

0x0A

Erase P-Flash

Sector

Erase all bytes in a P-Flash sector.

0x0B

Unsecure Flash

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.

0x0C

Verify Backdoor

Access Key

Supports a method of releasing MCU security by verifying a set of security keys.

0x0D

Set User Margin

Level

Specifies a user margin read level for all P-Flash blocks.

0x0E

Set Field Margin

Level

Specifies a field margin read level for all P-Flash blocks (special modes only).

0x01

Erase Verify All

Blocks

Verify that all EEPROM (and P-Flash) blocks are erased.

0x02

Erase Verify Block

Verify that the EEPROM block is erased.
