Initialization time
The S-7760A initializes at the same time when the power supply voltage is raised. Input instructions to the S-7760A
after initialization. The S-7760A does not accept any instruction during initialization.
Figure 35
shows the initialization time of the S-7760A.

Data hold time (tHD. DAT
= 0 ns)
If SCL and SDA of the S-7760A are changed at the same time, the timing which takes to reach this IC slightly lags due
to a load on the bus line. As a result, the change in the SDA precedes a falling edge of SCL so that S-7760A may
recognize a start/stop condition.
To avoid this, in the S-7760A, it is recommended to set the delay time of over 0.3
μs for a falling edge of SCL.
In its specs, it is described as the S-7760A works at 0 ns of data hold time, however, take account into the above
action in actual use.
