• Addressing Sequence of Interleave Mode
A column access is started in the input column address and is performed by inverting the address
bits in the sequence shown in the following table.
This field specifies the number of clock cycles from the assertion of the Read command to the first
read data.The minimum whole value of CAS# Latency depends on the frequency of CLK.The
minimum whole value satisfying the following formula must be programmed into this field.
