FIGURE 13-20: B
Programs the addressed code byte if the byte location has been successfully erased and not yet programmed.
Byte-Program operation is only allowed when the security lock is not activated on that flash memory block.
FIGURE 13-21: P
Programs the Security bits SB1, SB2 and SB3 respectively. Only a Chip-Erase will erase a programmed security bit.
