Result Register Overview
With different settings in the sequencer register 0x000B the FH3D02 can be used for various applications.
Depending on the TableSelect settings in register 0x000B the results in registers 0x0111 – 0x0114,
0x0120 – 0x124 can hold different magnetic values. The following table gives an overview about the
register content in different configurations.
