 MAIN MANUAL 
Regular SSI operation makes use differential signals. Thus, TMC4361A expects digital
differential serial clock input signals.
In order to disable the digital differential output signals, do as follows:
Action:
 Set serial_enc_out_diff_disable = 1 (Bit25 of GENERAL_CONF register 0x00).
Result:
Dedicated encoder signals are treated as single signals and every negated pin is
ignored.
TMC4361A is able to gray-encode SSI data automatically.
In order to enable gray-encoded SSI output data, do as follows:
Action:
 Set enc_out_gray =1 (Bit30 of ENC_IN_CONF register 0x07).
Result:
Encoder data output is gray-encoded.
