Datasheet

Upon clearing NVM_FSTAT[CCIF] to launch the program EEPROM command, the

user-supplied words will be transferred to the memory controller and be programmed if

the area is unprotected. The CCOBIX index value at program EEPROM command

launch determines how many bytes will be programmed in the EEPROM block. The

NVM_FSTAT[CCIF] flag is set when the operation has completed.

Table 4-48. Program EEPROM command error handling

NVM_FSTAT

ACCERR

Set if CCOBIX[2:0] < 010 at command launch

Set if CCOBIX[2:0] >101 at command launch

Set if command is not available in current mode (see Table 4-9)

Set if an invalid global address [23:0] is supplied

Set if the requested group of words breaches the end of the EEPROM

block

FPVIOL Set if the selected area of the EEPROM memory is protected

MGSTAT1 Set if any errors have been encountered during the verify operation

MGSTAT0

Set if any non-correctable errors have been encountered during the verify

operation

4.5.2.9.15 Erase EEPROM sector command

The erase EEPROM sector operation will erase all addresses in a sector of the EEPROM

block.

Table 4-49. Erase EEPROM sector command FCCOB requirements

CCOBIX[2:0] NVM_FCCOBHI parameters NVM_FCCOBLO parameters

000 0x12 Global address [23:16] to identify EEPROM block

001

Global address [15:0] anywhere within the sector to be erased. See Overview for EEPROM sector

size

Upon clearing NVM_FSTAT[CCIF] to launch the erase EEPROM sector command, the

memory controller will erase the selected EEPROM sector and verify that it is erased.

The NVM_FSTAT[CCIF] flag will set after the erase EEPROM sector operation has

completed.
