From 6b2700e2b1a03b7e0191f3dd9b34f8c51eea3c84 Mon Sep 17 00:00:00 2001 From: Aditya Gaddam Date: Fri, 31 Aug 2012 14:19:57 -0400 Subject: "Added ability to set callbacks for interrupts that get an argument. This argument can be the instance that needs to handle the interrupt, or just a random argument you might find useful later. Suggestions from mbolivar and iperry from pull53 on libmaple were taken into account.
