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 have been executed previously.
Except for 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 Volatile Configuration
Register (WVCR) instruction of the Extended SPI protocol.
