Table 6. Burst Configuration Register

Note: 1. X latencies can be calculated as: (tAVQV – tLLKH + tKHQV) + tSYSTEM MARGIN < (X -1) tK. (X is an integer number from 4 to 8 and tK

is the clock period), , where tLLKH is the value given by the master microcontroller timing specifications.

2. Y latencies can be calculated as: tKHQV + tSYSTEM MARGIN + tKHQV < Y tK.

3. tSYSTEM MARGIN is the time margin required for the calculation.
