The four steps of PWM mode enable, free-wheeling mode configuration, PWM channel mapping and PWM channels configuration ensure the proper configuration of PWM mode. Once the half-bridge is configured for the PWM generation, the half-bridge is enabled by enabling either of the high-side or low-side switch by individually setting the high-side enable bits (HBX_HS_EN) or low-side enable bits (HBX_LS_EN) in operation control registers (OP_CTRL_1, OP_CTRL_2 and OP_CTRL_3).
NOTE
The PWM is applicable to either of the high-side or low-side switch depending upon the HBX_HS_EN and HBX_LS_EN bits in OP_CTRL_X registers. In synchronous rectification mode, the opposite side switch will conduct in PWM off time.
