Bit
Volatile Configuration Register
Dummy clock cycle Volatile Configurations bits (VCR bits from 7 to 4)
The bits from 7 to 4 of the Volatile Configuration Register, as the bits from 15 to 12 of the
Volatile Configuration register, set the dummy clock cycles number after the fast read
instructions (in all the 3 available protocols). The dummy clock cycles number can be set
from 1 up to 15 as described in
operating frequency (the higher is the operating frequency, the bigger must be the dummy
clock cycle number, according to
the fast read instructions performance.
If the dummy clock number is not sufficient for the operating frequency, the memory reads
wrong data.
