From 0d40e5cace584c560091aea960f58cb1dc5a0dd9 Mon Sep 17 00:00:00 2001 From: Matthijs Kooijman Date: Wed, 25 Jun 2014 17:16:53 +0200 Subject: Support Atmega8 (and similar that define PE instead of UPE) again These chips were previously supported, but since parity error checking was added, this support has broken. Most chips define UPE0 (etc.) for the parity error bit. Some chips don't have numbered UARTS so only define UPE and even fewer define PE instead of UPE. This adds support for those chips again.
