  • Data[7..0] = low_div
  • Data[15..8] = high_div
  • total_div = high_div + low_div
  • Data[16] = bypass enable
    • When Data[16] = 1, bypass is enabled. The selected counter is bypassed with counter division value=1.
  • Data[17] = odd division
    • When Data[17] = 0, odd division is disabled. The selected counter duty cycle = high_div/total_div.
    • When Data[17] = 1, odd division is enabled. The selected counter duty cycle = (high_div - 0.5)/total_div.
