The main characteristic of this pre-filtering function is the ratio between the rise/fall time to the bit duration, t
The value of this ratio can be programmed between two pre-defined values in the RTParam_Stair configuration bit,
as shown in the Table 7.
When the pre-filtering function is enabled (RTParam_Filter set to “1”), only the following bit rates and frequency
deviations can be used:
