Always write zeroes to this field.
Sets latency from read cmd send to data receive from/to controller.
Sets the CAS latency linear value in 1/2 cycle increments. This sets an internal adjustment for the delay
from when the read command is sent from the EMI to when data will be received back. The window of time
in which the data is captured is a fixed length. The caslat_lin parameter adjusts the start of this data capture
window.
Not all linear values will be supported for the memory devices being used. Refer to the specification for the
memory devices being used.
For optimal synthesis behavior, the ODT path for a CAS latency of three is clocked at a 200 MHz clock
regardless of configured maximum speed.
