In Micron memory, the volatile as well as nonvolatile configuration registers are left with the default configuration of dummy cycles. That is, VCR[7:4] and NVCR[15:12] are set to 1111. The core behavior is based on this assumption only and if these dummy cycle register values are changed, the core behavior is not guaranteed.


RECOMMENDED:   Do not change the default Volatile Configuration Register (VCR) and Non Volatile Configuration Register (NVCR) configuration.

At the start of each new transaction, the core sends the respective command, address and required dummy cycles and then receives data.
