功能 #2789
若软件读取到“PWMx_Function_Assign_cfg”为0x02，则对应PWM通道关联HB功能，当收到HB功能指令时，PWM输出应立即从0%激活到对应的“PWMx_Target_Duty_Cycle_cfg”占空比。
(If the value of PWMx_Function_Assign_cfg is 0x02, the PWM channel is associated with HB. Upon receiving the HB command, the PWM output should be activated from 0% to the corresponding PWMx_Target_Duty_Cycle_cfg duty cycle.)
