4.2.3.1 Chip-Erase
The Chip-Erase command erases all bytes in both memory
partitions. This command is only allowed when EA#=0
(external memory execution).
Chip-Erase ignores the Security setting status and will
erase all settings on all pages and the different chip-level
security restrictions, returning the device to its Unlocked
state. The Chip-Erase command will also erase the boot
vector setting. Upon completion of Chip-Erase command,
the chip will boot from the default setting. See Table 4-2 for
the default boot vector setting.
4.2.3.2 Partition0-Erase
The Partition0-Erase command erases all bytes in memory
partition 0. All security bits associated with Page0-3 are
also reset.
4.2.3.3 Sector-Erase
The Sector-Erase command erases all of the bytes in a
sector. The sector size for the flash memory blocks is 128
Bytes. The selection of the sector to be erased is deter-
mined by the contents of SFAH and SFAL.
