The Response Phase End Point
The Response Phase ends when the Response Agent delivers a valid response to the Request Agent. This implies that the Response Agent can stall the Response Phase (i.e., insert wait states) until it is ready to present its response. One BCLK cycle after entry to the Response Phase, the Request Agent starts sampling RS[2:0]# at the start of each BCLK cycle. As long as the Idle response is detected, the Request Agent continues sampling RS[2:0]# at the start of each BCLK cycle until a response other than the Idle response is detected. Detection of a non-Idle response completes the transaction's Response Phase.
The spec doesn't place a limit on the number of wait states that may be inserted into the Response Phase of a ...
