Table 4-43. Valid set user margin level settings

CCOB

(CCOBIX = 010)

Level description

0x0000 Return to normal level

0x0001 User margin-1 level

0x0002 User margin-0 level

1. Read margin to the erased state

2. Read margin to the programmed state

Table 4-44. Set user margin level command error handling

NVM_FSTAT

ACCERR

Set if CCOBIX[2:0] != 010 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 an invalid margin level setting is supplied

FPVIOL None

MGSTAT1 None

MGSTAT0 None

Note

User margin levels can be used to check that NVM memory

contents have adequate margin for normal level read operations.

If unexpected results are encountered when checking NVM

memory contents at user margin levels, a potential loss of

information has been detected.

4.5.2.9.13 Erase verify EEPROM section command

The erase verify EEPROM section command will verify that a section of code in the

EEPROM is erased. The erase verify EEPROM section command defines the starting

point of the data to be verified and the number of bytes.

Table 4-45. Erase verify EEPROM section command FCCOB requirements

CCOBIX[2:0] NVM_FCCOBHI parameters NVM_FCCOBLO parameters

000 0x10 Global address [23:16] to identify the EEPROM block

001 Global address [15:0] of the first byte to be verified

010 Number of bytes to be verified
