This register has to be specified before initialization of the buffer
control because the Bank 1 free buffer pointer should have initial
value 130 for 16Mbit SDRAM, or, initial value 131 for 64Mbit
SDRAM.
CAS Latency for read operation:
2’b00: latency 1
2’b01: latency 2
2’b10: latency 3 (default)
SDRAMTYPE [0]

01H
This latency specifies the required delay between the CAS cycle and
the first read cycle. Note that the CAS latency has to be specified
before using RSDM in SDRAM initialization.
