Write Volatile Configuration Register
The Write Volatile Configuration register (WRVCR) instruction allows new values to be
written to the Volatile Configuration register. Before it can be accepted, a write enable
(WREN) instruction must previously have been executed.
Except for the parallelizing of the instruction code and the input data on the four pins DQ0,
DQ1, DQ2 and DQ3, the instruction functionality is exactly the same as the Write Volatile
Configuration Register (WRVCR) instruction of the Extended SPI protocol.
