NOTES:
1. This assumes CEN, CE1, CE2, CE2 are all true.
2. All Address, Control and Data_In are only required to meet set-up and hold time with respect to the rising edge of clock. Data_Out is valid after a clock-to-data delay
from the rising edge of clock.
NOTE:
1. Upon completion of the Burst sequence the counter wraps around to its initial state and continues counting.
