Signaling Requirements
As shown in Figure 2, valid data bits are defined as stable logic
0 or 1 condition on the data line during a clock HIGH (logic 1)
pulse. A transitioning data line during a clock HIGH pulse may
be interpreted as a start or stop pulse (it will be interpreted as
a start or stop pulse if the start/stop timing parameters are
met).

A write sequence is initiated by a “start bit” as shown in Figure
3. A “stop bit” signifies that a transmission has ended.
As stated previously, the W40S11-23 sends an “acknowledge”
pulse after receiving eight data bits in each byte as shown in
Figure 4.
