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 or Program cycle is in progress
is rejected without having any effect on the cycle that is in progress. A Program OTP cycle
cannot be paused by a Program/Erase Suspend (PES) instruction.
