STM32F401xB/C output a PWM signal on pin B14

[MArdm.1]

So, the issue is as follows, according to datasheet the timer for pin B14 AF1, which is the PWM signal I believe, is the TIM1_CH2N. I have gone out of my way to try and output something, I just can't seem to understand what the problem is

#define AF01 0x01
 
void ms_delay(int ms) {
  while (ms-- > 0) {
      volatile int x = 500;
      while(x-- > 0)
        __asm("nop");
  }
}
 
void setup() {
  RCC->AHB1ENR |= 1<<1; //Enable clock for GPIOB
  RCC->APB2ENR |= 1<<0; //Enable clock for TIM1
 
  GPIOB->MODER |= 1<<29; //Set pin B14 to alternate function
  GPIOB->MODER &= ~(1<<28);
 
  GPIOB->MODER |= 1<<0;
  GPIOB->OTYPER &= ~(1<<0);
 
  GPIOB->AFR[1] |= AF01<<24; //Set the alternate function register for pin 14 to 0001
 
  TIM1->PSC=0;
  TIM1->ARR=255;
  TIM1->CNT=0;
 
  TIM1->CCMR1 |= (1<<13)|(1<<14); //Set channel 2 to pwm mode 1
  TIM1->CCER |= 1<<4; //Enable channel 2
  TIM1->CCER |= 1<<6; //Enable channel 2N ??
  TIM1->CR1 |= 1<<0; // Counter enable for TIM1
  TIM1->BDTR |= 1<<15; 
 
  TIM1->CCR2 = 5;
  GPIOB->ODR |= 1;
}
 
void loop() {
  ms_delay(3000);
}

I am coding by putting value directly into registers sorry if this is less than readable, I can't use HAL or any other library, any help is much appreciated

Well, problem, found, in case anyone is interested, this code has no issues, it will activate the TIM1 Channel 2N, problem was external (:
