3.1.9.1.67.19 BiSS/SSI
Timeout that will be sent by the drive at the end of each BiSS/SSI frame, which informs the encoder that the
frame is over.
Refer to your encoder datasheet to check what is the minimum value for this parameter.

3.1.9.1.67.20 BiSS
Polynomial for the CRC calculation of the sensor data (SCD).
This value is obtained by writing the polynomial in binary representation.
For example: x^6 + x^3 + x^1 + x^0 is 0b1001011 = 0x4B = 75.
The default value of 67 (x^6 + x^1 + x^0 = 0b1000011 = 0x43) is the one used for most of the BiSS encoders.

3.1.9.1.67.21 BiSS
This value defines the maximum time to wait for the Start bit once the Ack bit was already received. If the
Start bit is not sent after this time, the error BisSrtBt is raised.
Check your encoder datasheet to find what's the typical or maximum value for this parameter.
It is advised to try to increase this number in case the error BisSrtBt appears, which is likely to happen
because the encoder needed more time to process the data before sending the Start bit.
