These registers allow the user to define the ranks and offsets that apply to the ranges defined by the LIMIT in the MC_RIR_LIMIT_CH registers. The mappings are as follows: RIR_LIMIT_CH{chan}[0] -> RIR_WAY_CH{chan}[3:0] RIR_LIMIT_CH{chan}[1] -> RIR_WAY_CH{chan}[7:6] RIR_LIMIT_CH{chan}[2] -> RIR_WAY_CH{chan}[11:10] RIR_LIMIT_CH{chan}[3] -> RIR_WAY_CH{chan}[15:14] RIR_LIMIT_CH{chan}[4] -> RIR_WAY_CH{chan}[19:18] RIR_LIMIT_CH{chan}[5] -> RIR_WAY_CH{chan}[23:22] RIR_LIMIT_CH{chan}[6] -> RIR_WAY_CH{chan}[27:26] RIR_LIMIT_CH{chan}[7] -> RIR_WAY_CH{chan}[31:28] Device: 4 Function: 2 Offset: 80h, 84h, 88h, 8Ch, 90h, 94h, 98h, 9Ch, A0h, A4h, A8h, ACh, B0h, B4h, B8h, BCh, C0h, C4h, C8h, CCh, D0h, D4h, D8h, DCh, E0h, E4h, E8h, ECh, F0h, F4h, F8h, FCh Access as a Dword Bit 13:4 3:0 Type RW RW Reset Value Description 0 OFFSET. This field defines the offset used in the rank interleave. This is a 2's complement value. 0 RANK. This field defines which rank participates in WAY(n). If MC.CLOSEDPAGE=1, this field defines the DRAM rank selected when MemoryAddress[7:6]=(n). If MC.CLOSEDPAGE=0, this field defines which rank is selected when MemoryAddress[13:12]=(n). (n) is the instantiation of the register. This field is organized by physical rank. Bits [3:2] are the encoded DIMM ID(slot). Bits [1:0] are the rank within that DIMM. Datasheet 89
