Note 4: DS3 mode.
Note 5: E3 mode.
Note 6: STS-1 mode.
Note 7: In normal mode, TPOS/TNRZ and TNEG are sampled on the rising edge of TCLK and RPOS/RNRZ and RNEG/RLCV are updated on
Note 8: In inverted mode, TPOS/TNRZ and TNEG are sampled on the falling edge of TCLK and RPOS/RNRZ and RNEG/RLCV are updated on
