1. Global address [23] selects between flash (0) or EEPROM (1) block, that can otherwise eventually share the same

address on the MCU global memory map.

Upon clearing NVM_FSTAT[CCIF] to launch the erase verify block command, the

memory controller will verify that the selected flash or EEPROM block is erased. The

NVM_FSTAT[CCIF] flag will set after the erase verify block operation has completed. If

the block is not erased, it means blank check failed and both NVM_FSTAT[MGSTAT]

bits will be set.

Table 4-23. Erase verify block command error handling

FSTAT

ACCERR

Set if CCOBIX[2:0] != 000 at command launch

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

FPVIOL None

MGSTAT1

Set if any errors have been encountered during the read or if blank check

failed

MGSTAT0

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

or if blank check failed

4.5.2.9.3 Erase verify flash section command

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

memory is erased. The erase verify flash section command defines the starting point of

the code to be verified and the number of longwords.

Table 4-24. Erase verify flash section command FCCOB requirements

CCOBIX[2:0] NVM_FCCOBHI parameters NVM_FCCOBLO parameters

000 0x03 Global address [23:16] of flash block

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

010 Number of long words to be verified

Upon clearing NVM_FSTAT[CCIF] to launch the erase verify flash section command,

the memory controller will verify that the selected section of flash memory is erased. The

NVM_FSTAT[CCIF] flag will set after the erase verify flash section operation has

completed. If the section is not erased, it means blank check failed and both

FSTAT[MGSTAT] bits will be set.
