Refresh Interval
This 13-bit field is used to enable refresh and set the refresh period.
When set to zero, refresh cycles are disabled. When set to non-zero,
refresh cycles are enabled, and are requested internally based on this
programmed value. RP and RC control the timing waveform of refresh
cycle. This field is set to zero on the hard reset, so refreshes are disabled
after a hard reset. This field is a one-based number, and is programmed
in CLK period.(1/CLK)
