Each Rank has its own ODT pin that fans out to all the memory parts * in that rank. System designers may prefer different combinations of ODT ON's for reads * into different ranks. Octeon supports full programmability by way of the mask register below. * Each Rank position has its own 8-bit programmable field. * When the controller does a read to that rank, it sets the 4 ODT pins to the MASK pins below. * For eg., When doing a read into Rank0, a system designer may desire to terminate the lines * with the resistor on Dimm0/Rank1. The mask RODT_D0_R0 would then be [00000010]. * Octeon drives the appropriate mask values on the ODT pins by default. If this feature is not * required, write 0 in this register. Note that, as per the DDR3 specifications, the ODT pin * for the rank that is being read should always be 0. * * Notes: * - Notice that when there is only one rank, all valid fields must be zero. This is because there is no * "other" rank to terminate lines for. Read ODT is meant for multirank systems. * - For a two rank system and a read op to rank0: use RODT_D0_R0<1> to terminate lines on rank1. * - For a two rank system and a read op to rank1: use RODT_D0_R1<0> to terminate lines on rank0. * - Therefore, when a given RANK is selected, the RODT mask for that RANK is used. * * DFM always reads 128-bit words independently via one read CAS operation per word. * When a RODT mask bit is set, DFM asserts the OCTEON ODT output * pin(s) starting (CL - CWL) CK's after the read CAS operation.

Octeon supports full programmability by way of the mask register below. * Each Rank position has its own 8-bit programmable field. * When the controller does a write to that rank, it sets the 4 ODT pins to the MASK pins below. * For eg., When doing a write into Rank0, a system designer may desire to terminate the lines * with the resistor on Dimm0/Rank1. The mask WODT_D0_R0 would then be [00000010]. * Octeon drives the appropriate mask values on the ODT pins by default.

Then, OCTEON normally continues to assert the ODT output pin(s) for five * more cycles - for a total of 6 cycles for the entire word write - satisfying the 6 cycle DDR3 * ODTH8 requirements.
