I started designing the development board for STM32F427VIT6 of LQFP100 package. Its has multiple USART and UART pins.
The USART names in the datasheets are USART1, USART2, USART3, UART4, UART5, USART6 UART7 and UART8.
In pin out table pin PA0 and PA1 are UART4_TX and UART4_RX respectively. PC10 and PC11 are also UART4_TX and UART4_RX. Same case with USART and SPI pins. Different pins having the repeated names.
Please explain the reason and how to use these pins.
