Hello,
once i set MOVC-0 and LockBit-0 and flashed chip using universal programmer, is it possible to flash next time or not? i means after setting above bits, will chip in ROM mode or possible to flash another firmware?
Regard,
Nilesh

Hi Nilesh,
No, but some people are still able to bypass the lock.
The new models will be better in terms of code protection generally.

Hello Danny,
I saw datasheet saying bits can be reset when all errase operation called. does it mean we can reset config bits and can program flash again ?

Hi Nilesh,
Okay, I'll ask the engineer to confirm this.
Please understand that we have to wait for a few days because of the Lunar New Year holiday.

Hi
Could I know which universal programmer do you use?
In normal circumstances, it will erase-all opeation before program.
Thanks.

Hi Nilesh,
According to the reply, erase all will be executed while programming by the universal programmer.
So the lock bit does not affect the programming of new firmware.
