Hi,

At Atxmega32E5 I need sometimes in program to use PORTD.3 for other putpose. When I use Usartd0_ctrlb = &B00000000 then I disable USART but pin is in low state and I can not
set it to high level. When I use Usartd0_ctrlb = &B00001000 (TXEN) then USART is not active. Where is problem ?

Thanks

usartd0_ctrlb.3=0 'disable TX
config PORTD.3=output
portd.3= someState

and to re-enable, just write ctrlb bit 3 to 1.
