please Answer the following questions

An existing timer library is to be added. The following functional prototype is given. 1 2 3 void ConfigPWMChannel (TIM TypeDef const * const timer, const uint8_t pwm Mode, const uint8_t pwmChannel); With the following description TIM_TypeDef Structure for all registers that are assigned to a timer. pwmMode contains the specific number of the selected PWM mode. pwmChannel contains the specific number of the selected channel. a) First, only enter the commands that check whether the transferred parameter Timer corresponds to Timers 2 or 1. If this is not the case, a suitable standard value should be used. b) Now enter the required commands so that the corresponding mode is set correctly. Implement the case for Channel 4. C) Make each (a) and (b) free of syntax errors. Notice. This only applies to a complete solution of (a) and (b) respectively
