Program Verification/Code Protection
ROM Devices
If the code protection bit(s) have not been programmed, the on-chip program memory can be
read out for verification purposes.
When a ROM device also has Data EEPROM memory, an additional code protect configuration
bit may be implemented. The program memory configuration bit is submitted as part of the ROM
code submittal. The Data EEPROM memory code protect configuration bit will be an EEPROM
bit. When ROM devices complete testing, the EEPROM data memory code protect bit will be pro-
grammed to the same state as the program memory code protect bit. That is data EEPROM code
protect is off, when program memory code protect is off, and data EEPROM code protect is on
for all other selections.
In applications where the device is code protected and the data EEPROM needs to be pro-
grammed before the application can be released, the data EEPROM memory must have the
entire data EEPROM memory erased. The device programming specification details the steps to
do this. Microchip device programmers implement the specified sequence. Once this sequence
is complete, the Data EEPROM memory code protect is disabled. This allows the desired data
to be programmed into the device. After programming the data EEPROM memory array, the data
EEPROM memory code protect configuration bit should be programmed as desired.
Note:
Microchip does not recommend code protecting windowed devices.
