STM32F101RD TIM5 Channel 3 PWM Output

We are using the STM32F101RD component.  We've configured TIM5, channels 2, 3 and 4.  Channels 2 and 4 work as expected.  Channel 3 is always high (we have 10k pull ups on the line) and is never driven low by the PWM.  This is the same configuration for all three channels.

If we set the pins manually as GPIO, we can toggle appropriately.  Is there anything special/different about TIM5, channel 3 compared to the others? #tim5-stm32f101

Pin PA2?

Do you perhaps have USART2 enabled? You're asking us to guess a lot of things about your board, and how you're configuring the TIM and pins.
