why is there a delay between (DR register written) and (data really showed) in UART on STM32F103CB?

I'm curious about the delay time between the title mentioned, I toggled an IO when I wrote data into UART->DR, the delay time varies from 3 micro seconds to 10x micro seconds int main(void) { /* initial code generated by STMCubeMX */ …

STM32F103 using MISO pin when SPI in Half-Duplex mode

I'm using STM32F103C8T6 with SPI1 remapped and in half-duplex mode (MISO pin unused by SPI). I'd like to use MISO pin (PB4) for PWM generation by TIM3 remapped but I can not get it working while SPI1 is clocked. So is there a way to use MISO pin of…
