Once a bit of the OTP memory has been programmed to '0', it can no longer be set to '1'.
Therefore, as soon as bit 0 of byte 64 (control byte) is set to '0', the 64 bytes of the OTP
memory array become read-only in a permanent way.
Any Program OTP (POTP) instruction issued while an Erase, Program or Write cycle is in
progress is rejected without having any effect on the cycle that is in progress.
