Layer. Selection of which PHY layer device is being read is made by the value on RADR[4:0] the cycle before RENB is asserted and affects the RDAT[15:0], RSOC, and RPRTY signals. The value of RADR[4:0] selects the PHY being polled for the RCA signal, and all devices not corresponding to this address must tri-state its RCA output. These multi-PHY operations are directly supported by the S/UNI-QUAD.
