Additive Latency (MR1)
A posted /CAS read or write command when issued is held for the time of the Additive Latency (AL) before it is
issued inside the device. The read or write posted /CAS command may be issued with or without auto precharge.
The Read Latency (RL) is controlled by the sum of AL and the /CAS latency (CL).
The value of AL is also added to compute the overall Write Latency (WL).
MRS (1) bits A4 and A3 are used to enable Additive latency.
