Write Volatile Enhanced Configuration Register
The Write Volatile Enhanced Configuration register (WRVECR) instruction allows new
values to be written to the Volatile Enhanced 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 four pins DQ0,
DQ1, DQ2 and DQ3, the instruction functionality is exactly the same as the Write Volatile
Enhanced Configuration Register (WRVECR) instruction of the Extended SPI protocol,
please refer to
details.
