TSEQ3<3:0>: Tune Sequence Value #3 bits
When PWM ROLL<2:0> = 011, this field is used to tune the FRC instead of TUN<3:0>
TSEQ2<3:0>: Tune Sequence Value #2 bits
When PWM ROLL<2:0> = 010, this field is used to tune the FRC instead of TUN<3:0>
TSEQ1<3:0>: Tune Sequence Value #1 bits
When PWM ROLL<2:0> = 001, this field is used to tune the FRC instead of TUN<3:0>
