Note
1. X indicates bits that have not yet been assigned to a function. Their meaning is ‘don’t care’. They should be written
The following sub-sections provide a detailed description of the slave receiver registers:
10.3.1
10.3.1.1
If the automatic gain control function is switched off in the General Configuration Register, the contents of this register
will define a fixed gain of the AGC stage. The input voltages given are meant to generate a full-scale output from the SIF
ADC. If automatic gain control is on, the contents of this register is ignored.
It should be noted that the input voltages should be considered as approximate target values.
