14.4.3.7.3
This parameter, controlled by LSDMR[CL] for latency of 1, 2, or 3 and by LCRR[ECL] for latency of
more than 3, defines the timing for first read data after a column address is sampled by the SDRAM.
14.4.3.7.4
This parameter, controlled by LSDMR[WRC], defines the earliest timing for a PRECHARGE command
after the last data was written to the SDRAM.
