Register Description 2.10.16 MC_CHANNEL_0_RCOMP_PARAMS MC_CHANNEL_1_RCOMP_PARAMS MC_CHANNEL_2_RCOMP_PARAMS This register contains parameters that specify Rcomp timings. Device: 4, 5, 6 Function: 0 Offset: 98h Access as a Dword Bit Type 16 RW 15:10 RW 9:4 RW 3:0 RW Reset Value Description RCOMP_EN. 1 Enable Rcomp. When set, the Integrated Memory Controller will do the programmed blocking of requests and send indications. RCOMP_CMD_DCLK. 2 Delay from the start of an RCOMP command blocking period in which the command rcomp update is done. Program this field to 15 for all configurations. RCOMP_LENGTH. 9 Number of Dclks during which all commands are blocked for an RCOMP update. Data RCOMP update is done on the last DCLK of this period. Program this field to 31 for all configurations. RCOMP_INTERVAL. 0 Duration of interval between Rcomp in increments of tRefI. Register value is tRefI-1. For example a setting of 0 will produce an interval of tRefI. 2.10.17 MC_CHANNEL_0_ODT_PARAMS1 MC_CHANNEL_1_ODT_PARAMS1 MC_CHANNEL_2_ODT_PARAMS1 This register contains parameters that specify ODT timings. All values are in DCLK. Device: 4, 5, 6 Function: 0 Offset: 9Ch Access as a Dword Bit Type 26:24 RW 23:20 RW 19:16 RW 15:12 RW 11:8 RW 7:4 RW 3:0 RW Reset Value Description TAOFD. 0 ODT turn off delay. MCODT_DURATION. 6 Controls the duration of MC ODT activation. BL/2 + 2. 4 MCODT_DELAY. Controls the delay from Rd CAS to MC ODT activation. This value is tCAS-1. 5 ODT_RD_DURATION. Controls the duration of Rd ODT activation. This value is BL/2 + 2. ODT_RD_DELAY. 0 Controls the delay from Rd CAS to ODT activation. This value is tCAS-tWL. ODT_WR_DURATION. 5 Controls the duration of Wr ODT activation. value is BL/2 + 2. ODT_WR_DELAY. 0 Controls the delay from Wr CAS to ODT activation. This value is always 0. 72 Datasheet
