Chip Erase The Chip Erase will erase the Flash and EEPROM
(1)
memories plus Lock bits. The Lock
bits are not reset until the Program memory has been completely erased. The Fuse bits
are not changed. A Chip Erase must be performed before the Flash and/or EEPROM
are re-programmed.
Note: 1. The EEPROM memory is preserved during Chip Erase if the EESAVE Fuse is
programmed.
