Does anyone have problems with the USART when only a reset is performed and not a power down/up?
My code waits for the USART_DREIF_bm flag to be set indicating that it is ok to give the USART a byte.
If I start from power down, everything works. If I do a reset via the debugger or micro reset, the flag is never set.
I thought I'd ask the general question first. If more code is needed I will provide.
