We have below technical queries regarding ATxmega128A3U-AUR and ATxmega128A1U-AU microcontrollers.
- In the data sheet it is mentioned that there are 7 and 8 UARTs respectively however, in the data sheet while looking at the Pin out description, it can be seen that there are only 2 UARTS (UART0 and UART1) with multiplexed pins on different ports. Can you please let us know if we can use more than 2 UARTS (in our case we wish to use 3) in the design which should work indepnedently simulataneously?
- Regarding evaluation board STK600 for ATxmega128A1U-AU, it does not contain the USB functionality in it. Can you please let us know the evaluation board which contain USB functionality as well.
