Hello, I use USART1 routed to PA9/PA10 (AF1 as per data sheet), so executing the line
SYSCFG->CFGR1 |= (SYSCFG_REMAP_PA11 | SYSCFG_REMAP_PA12);
should present the GPIOs PA9 and PA10 to pins 16 and 17 of the TSSOP20 package. Right?
Well, pins 16 and 17 continue to carry PA11/PA12 no matter what the state of the two REMAP bits. I suppose these control a MUX each (as opposed to multiple bonding like e.g.PB3/4/5/6)?
Is there anything I am missing? Thank you!
