9.4.1 Flowchart explanation
9.4 I
The following flowcharts describe how to:
The image rejection calibration as well as RF tracking filters calibration must be launched
the way explicitly described in the flowchart. If not done this way, it may result in bad
calibration or even blocking the TDA18211HD, which makes it impossible to communicate
via the I
For proper internal initialization, switching to Normal mode also requires a single I
sequence from subaddresses 03h to 0Fh.
This section provides instructions for reading the flowcharts.
