3.3.6. DMC CAS Latency Register at 0x0014

The read/write dmc_cas_latency Register sets the CAS latency in memory clock cycles. It can only be read and written in the Config or Low-power state. Figure 3.11 shows the register bit assignments.

cas_latencyCAS latency in memory clock cycles.
[0]cas_half_cycle

Encodes whether the CAS latency is half a memory clock cycle more than the value given in bits [3:1]:

1’b0 = Zero cycles offset to value in [3:1].

1’b1 = Half cycle offset to value in [3:1].
