| 4:0 | DEVAD | RW | 0 | Device Address: Bits[4:0] are the device address, DEVAD, that directs any accesses of ADDAR Register 0x000E – Address/Data Register to the appropriate MMD. Specifically, the DP83TC811S-Q1 uses the vendor specific DEVAD [4:0] = "11111" for accesses to registers 0x04D1 and lower. For MMD1 access, the DEVAD[4:0] = '00001'. All accesses through registers REGCR and ADDAR should use the DEVAD for either MMD or MMD1. Transactions with other DEVAD are ignored. |
