[7:6] PM_2A[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_2A[5:0]: PWM shift
The PWM waveform could be shifted by (PS_2A * clock period / 64)
