4.7. Registers

The AVMM Responder interface for the JESD204B supports 0 cycle write transaction and 1 cycle read transaction. There is no support for wait-state feature (the avs_waitrequest signal is tied to 0). It does not support byte enable hence all transaction will be based on 32bit width field. The interface does not support burst transaction and variable latency.

Each write transfer has a writeWaitTime of 0 cycle while a read transfer has a readWaitTime of 1 cycle and readLatency of 1 cycle.

JESD204B TX registers residing in 1 reset domain and JESD204B RX registers residing in another reset domain. JESD204B TX/RX will only decode 8-bit addressing (byte addressing) with address range up to 0xFFh (256 Byte).
