Hello, I would like to have access to uart1 and USB on stm32f105rc, but they both are on the same pins.
My question is that, if I remap the USART1 to alternate pins, USB still working on original pins.

I have readed this on the reference manual:

To optimize the number of peripherals available for the 64-pin or the 100-pin or the 144-pin
package, it is possible to remap some alternate functions to some other pins. This is
achieved by software, by programming the AF remap and debug I/O configuration register
(AFIO_MAPR) on page 184. In this case, the alternate functions are no longer mapped to
their original assignations.

Thank you.
