Table 4. Burst Configuration Register
Note: 1. 4 - 2 - 2 - 2 (represents X-Y-Y-Y) is not allowed.
2. X latencies can be calculated as: (tAVQV – tLLKH + tQVKH) + tSYSTEM MARGIN < (X -1) tK. (X is an integer number from 4 to 8 and tK
is the clock period).
3. Y latencies can be calculated as: tKHQV + tSYSTEM MARGIN + tQVKH < Y tK.
4. tSYSTEM MARGIN is the time margin required for the calculation.
