PB14 and PC9 of STM32G070RBT6 can't use PWM at the same time

[sunnyguhz]

I set PWM for PB14 and PC9 of STM32G070RBT6, but only one of them can work.
What can I do to make them work simultaneously?

void setup() {
  analogWriteResolution(12);  
  analogWriteFrequency(10000);  
  pinMode(PB14, OUTPUT);
  pinMode(PC9, OUTPUT);
}

void loop() {
  analogWrite(PB14, 2048);
  analogWrite(PC9, 1024);
  delay(1);
}

Hi @sunnyguhz
This is normal:

Both pin used TIM1 by default.
Simply suffix one by _ALT1 to not use the same TIM instance

  analogWrite(PB14, 2048);
  analogWrite(PC9_ALT1, 1024);
