U Phase Combinational Circuit (PFN001)
The U phase combination circuit generates variable dead time range pulses
(FN00 A and FN01 A) that are used to insert the dead time pulse generated by
the one-shot pulse output function into the triangle wave PWM generated by
the triangle wave PWM output function with the dead time.
Table 24-16 shows the relation between the inputs (UIN and U2) and the
outputs (UO1 and UO2) of the combinational circuit.

Description of variable dead time range pulse
Variable dead time range pulses are the pseudo pulses that are inserted into
the PWM output provided by the triangle wave PWM output function with the
dead time of TAUB and that are modeled on the dead time pulses that are
generated in the range where duty cycle is close to 100% or 0% in PWM
output in HT-PWM mode of TSG2.
Note:
Setting of PIC0REG201k (k = 16 to 19) depends on the active level of the U or
UB phase output of the triangle wave PWM generated by the triangle wave
PWM output function with the dead time.
