36.5.3.6 Write (Program) Considerations
Each word of the User area can be written only once. It is possible to write a packet payload partially and/or update a packet payload already written.
The packet to write (either the header or the payload) may contain some bits already at ‘1’. In this case, a dummy packet can be used to write the packet in a different location. The OTPC may also be able to fix the ‘1’ already written if this bit also matches the packet to write. Thus before writing any new packet, it is necessary to proceed to a read at the last address.
