RC (Row Cycle Time)
This 4-bit field specifies the number of cycles for a refresh command. It
also specifies the number of cycles between bank activation commands
to the same bank.

CL (CAS Latency)
This value is used to program the SDRAM devices during the
Initialization sequence, and internally by the SDRAM controller.
0 = 1 clock
1 = 2 clocks

Row Hit Enable
This value is used to enable the checking of the row address from
internal logic matched with row address of destination SDRAM. It may
cause one or two clock delay in accessing SDRAM but will make sure
that correct operation will be happening.
0 : Do not check whether row address is HIT or not.
1 : Check whether row address is HIT or not.

Refresh Interval
This register includes refresh interval value and MCLK tuning control reginter.
