From 95c44ec485b46ffb43dbdaa299f1491a500fdadf Mon Sep 17 00:00:00 2001 From: Detlev Zundel Date: Wed, 7 Oct 2009 16:38:05 +0200 Subject: tqm5200: Correct comment and code in post_hotkeys_pressed. This fixes the code and the comment according to the original intent of doing an intensive memory test when PSC6_3 is pulled low on the STK52xx. Notably PORT_CONFIG will be overridden with this correct code now, so beware. The original code only worked by coincidence depending on the PORT_CONFIG setting from the header file. The new code was tested to ensure that the (undocumented) memory test still works on the STK52x. Signed-off-by: Detlev Zundel CC: Martin Krause Minor white-space cleanup.
