Volatile Configuration Register
The Volatile Configuration Register (VCR) affects the memory configuration after execution
of Write Volatile Configuration Register (WRVCR) instruction: it overwrites the memory
configuration set at POR by the Non Volatile Configuration Register (NVCR) to define the
dummy clock cycles number and makes the device ready to enter in the required XIP mode.

To optimize instruction execution (FASTREAD,
DOFR,DIOFR,QOFR, QIOFR, ROTP) according
to the frequency
To make the data on DQ0 during the first dummy
clock NOT “Don’t Care.” For devices with feature
set digit equal to 2 or 4 in the part number (Basic
XiP), this bit is always Don't Care"
