Flowchart of Initialization at Power-on and Example of Real-time Data Set-up
Figure 50
shows the flowchart of initialization at power-on and an example of real-time data set-up. Regarding how to apply
power, refer to “
Power-on Detection Circuit and Register Status”
. It is unnecessary for users to comply with this
flowchart of real-time data strictly. And if using the default data at initializing, it is also unnecessary to set up again.
