Figure 92. Read Volatile Configuration Register instruction sequence QIO-SPI
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. In case of Fast POR, the WREN
instruction is not required because a WREN instruction gets the device out from the Fast
POR state (See
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
Configuration Register (WRVCR) instruction of the Extended SPI protocol, please refer to
