The Refresh Timer register is used to specify the period between refresh
cycles.
RSVD:
Refcnt:
When power on reset is asserted, the values of the boot mode option pins
shown in
latched values. This register can be read to determine which memory
configuration was used during the boot process.

Reserved. - Unknown During Read
Refresh Count - Read/Write
The value written to this field specifies, in multiples of the
period of HCLK, the time period between refresh cycles.
For example, if the period of HCLK is 20 ns, this field
should be written to 0x320 (decimal 800) to generate a
16 ms refresh period. On reset, this field defaults to
0x0080 (decimal 128) to generate a 2.56 ms refresh
period, but it must be written during the SDRAM
initialization routine to the appropriate value for the
SDRAM devices. If this field is written to 0x0000, no
refresh cycles are issued.
