TSEQ7<3:0>: Tune Sequence value #7 bits
When PWM ROLL<2:0> = 111, this field is used to tune the FRC instead of TUN<3:0>
TSEQ6<3:0>: Tune Sequence value #6 bits
When PWM ROLL<2:0> = 110, this field is used to tune the FRC instead of TUN<3:0>
TSEQ5<3:0>: Tune Sequence value #5 bits
When PWM ROLL<2:0> = 101, this field is used to tune the FRC instead of TUN<3:0>
TSEQ4<3:0>: Tune Sequence value #4 bits
When PWM ROLL<2:0> = 100, this field is used to tune the FRC instead of TUN<3:0>
Unimplemented: Read as ‘0’
When PWM ROLL<2:0> = 111, this field is used to tune the FRC instead of TUN<3:0>
