Complementary Low Side and high Side Chopper)
6.9.3 PWM_ALIGNMENT Configuration Register
This register commonly determines the alignment of the three PWM units. The alignment can be
programmed left aligned, centered, or right aligned (pls. refer Figure 36, Figure 37, and Figure 38).

6.9.4 POLARITIES Configuration Register
The PWM signals of the three are of positive logic. So, logical one level means ON and logical zero level
means OFF. Depending on the MOS-FET drivers, switching on a MOS-FET might require an inverted
logical level. The polarities configuration register determines the switching polarities for the high side
MOS-FETs and switching polarities for the low side MOS-FETs.
