A write sequence is valid only when both the following conditions
are met. This prevents spurious writes that might lead to data corruption.
- 1.All NVM read, write, and erase operations are enabled with the
NVMCMD control bits. It is suggested to have the NVMCMD bits cleared at all times except
during memory writes. This prevents memory operations if any of the control bits are set
accidentally.
- 2.The NVM unlock sequence must be performed each time before all
operations except the memory read operation.
