Notes:
1) Wait 1.0 µs between any Reads or Writes after writing a Control Word with a Clear (D7=1). Wait 1.0 µs
between any Reads or Writes after Clearing a Control Word with a Clear (D7=0). All other Reads and
Writes can be back to back.
2) All input voltages are (VIL=0.8 V, VIH=2.0 V)
3) Data out voltages are measured with 100 pF on the data bus and the ability to source = –40 µA and
sink=1.6 mA The rise and fall times are 60 ns. VOL=0.4 V, VOH=2.4 V.
