6.8.5.16 Complementary mode
Complementary mode is enabled when the pair channel corresponding PWMMODEn
(PWM_CTL1[26:24]) bit set to 1. In this mode there are 3 PWM generators utilized for
complementary mode, with total of 3 PWM output paired pins in this module. In Complementary
modes, the internal odd PWM signal must always be the complement of the corresponding even
PWM signal. PWM_CH1 will be the complement of PWM_CH0. PWM_CH3 will be the complement
of PWM_CH2 and PWM_CH5 will be the complement of PWM_CH4 as shown in Figure 6.8-21.

6.8.5.17 PWM Output Function
Based on the output mode, there are two output functions: group and synchronous functions for
advanced output control. Group function, forces the PWM_CH2 and PWM_CH4 synchronous with
PWM_CH0 generator and forces the PWM_CH3 and PWM_CH5 synchronous with PWM_CH1,
may simplify updating duty control in DC and BLDC motor applications. Besides, Synchronous
