6.6.4
For protection, the write initiate sequence for NVMKEY
must be used to allow any erase or program operation
to proceed. After the programming command has been
executed, the user must wait for the programming time
until programming is complete. The two instructions
following the start of the programming sequence
should be NOPs.
