Write NV Configuration Register
The Write Non Volatile Configuration register (WRNVCR) instruction allows new values to
be written to the Non Volatile Configuration register. Before it can be accepted, a write
enable (WREN) instruction must previously have been executed.
Apart form the parallelizing of the instruction code and the input data on the two pins DQ0
and DQ1, the instruction functionality is exactly the same as the Write Non Volatile
Configuration Register (WNVCR) instruction of the Extended SPI protocol, please refer to
