• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

16 KByte Flash Module (S12FTMRG16K1V1)
21.4.5
Only the operations marked ‘OK’ in
Flash and EEPROM blocks. Some operations cannot be executed simultaneously because certain hardware
resources are shared by the two memories. The priority has been placed on permitting Program Flash reads
while program and erase operations execute on the EEPROM, providing read (P-Flash) while write
(EEPROM) functionality.

Mass Erase
A ‘Margin Read’ is any read after executing the margin setting commands
‘Set User Margin Level’ or ‘Set Field Margin Level’ with anything but the
‘normal’ level specified. See the Note on margin settings in

Section
Erase all EEPROM (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 EEPROT register are set prior to
launching the command.
Erase a EEPROM (or P-Flash) block.
An erase of the full EEPROM block is only possible when DPOPEN bit in the EEPROT
register is set prior to launching the command.
Supports a method of releasing MCU security by erasing all EEPROM (and P-Flash)
blocks and verifying that all EEPROM (and P-Flash) blocks are erased.
Specifies a user margin read level for the EEPROM block.
Specifies a field margin read level for the EEPROM block (special modes only).
Verify that a given number of words starting at the address provided are erased.
Program up to four words in the EEPROM block.
Erase all bytes in a sector of the EEPROM block.
