WebI have a CLOCK which is generated with a MMCM who's phase I can control but nominally it is -76 degrees from an internal reference clock. This pin is sparsely (< 10 flops) used internal to the FPGA but it is driven to a PIN for use with external logic. I am trying to write a constraint that I can use this clock as both my timing reference, using … WebThe f411re’s USART1 and USART6 should be capable of operating at a target baud rate of 3686400 since they run off of the APB2 bus. The APB2 bus has an f_pclk of 100MHz when the MCU is clocked at 100 MHz. USART2 runs off of the APB1 bus, which only has an f_pclk of 50 MHz.
