Resolved! STM32F446 TIM2 CCR1 and DMAR registers appear tied together.

I've been trying to get TIM2 PWM (or even OC) to produce an output. When looking at the registers, using openocd w telnet, I find that setting 0x40000000 (the CR1 register) with 0x81 also sets the 0x4000004C (the DMAR) register. The reverse is the sa...
