4.2.4 In-Application Programming Mode
Commands
All of the following commands can only be initiated in the
IAP mode. In all situations, writing the control byte to the
SFCM register will initiate all of the operations. All com-
mands will not be enabled if the security locks are enabled
on the selected memory block.
The Program command is for programming new data into
the memory array. The portion of the memory array to be
programmed should be in the erased state, FFH. If the
memory is not erased, it should first be erased with an
appropriate Erase command. Warning: Do not attempt to
write (program or erase) to a block that the code is cur-
rently fetching from. This will cause unpredictable pro-
gram behavior and may corrupt program data.
4.2.4.1 Chip-Erase
The Chip-Erase command erases all bytes in both memory
blocks. This command is only allowed when EA#=0 (exter-
nal memory execution). Additionally this command is not
permitted when the device is in level 4 locking. In all other
instances, this command ignores the Security Lock status
and will erase the security lock bits and re-map bits.
