Writing value to UCSRA register has no effect, that is subsequent read shows old value. Moreover writing some bits should generate interrupts according to the datasheet but actually nothing happens. Credits to Andrey Vasilyev for noticing this. Code analysis proves HWUart::SetUsr method doesn't store the new value (like corresponding SetUcr).
