PM_3B[1:0]
PS_3B[5:0]
[7:6] PM_3B[1:0]: PWM mode
00: generate a rising edge using a down carrier
01: generate a falling edge using an up carrier
10: hybrid mode: alternation of modes 00 and 01
11: hybrid mode: alternation of modes 01 and 00
[5:0] PS_3B[5:0]: PWM shift
The PWM waveform could be shifted by (PS_3B * clock period / 64)

MP_ZERO_4
MIN_PLS_4[3:0]
[7] AZPLS_4
1: avoid zero pulse
[6] TERNARY_4
1: ternary modulation
[5] HALFB_4
1: 4B is modulated as null signal
[4] MP_ZERO_4
1: apply the minimum pulse settings also for values near 0
[3:0] MIN_PLS_4[3:0]
Minimum pulse length = clock period * (MIN_PLS_4 + 1)
