Hi. For example, if I will lock flash page in Tiva C from writing/erasing permanently, can I unlock it after that?

Hello Tim,

You would need to run the unlock sequence which will return the device to factory condition if the bits are committed. If not then only a Power On Reset will turn a bit from 0 to 1.
