/*
 * Init_Target() is the first function called from Application_Initialize().
 * But unfortunately, our TCS211 semi-src has this function in a binary lib.
 * I was able to find a conditioned-out version in the LoCosto source that
 * seems to be a fit - so I'm going to massage it a bit to match the sequence
 * of operations seen in the disassembly of our reference binary.
