2) Software reset
Please execute software reset in care that the device is an unexpected state after power up and/or the command
input need to be reset.
There are some kinds of software reset. Here we show three types of example as follows.
During dummy clock, please release SDA bus (tied to V
CC
by pull up resistor).
During that time, the device may pull the SDA line LOW for acknowledge or outputting or read data.
If the master controls the SDA line HIGH, it will conflict with the device output LOW then it makes a current overload. It
may cause instantaneous power down and may damage the device.
