*
*
*	DESCRIPTION:
* 
*	This file is used by main.c and configures the Micron Image Sensor to
*	capture images.
*	
* 	NOTE:
*	>> If it is a 9V032 sensor, it issues dummy writes to enable the I2C
*	>> Both the 9V032 and the 9V022 use the same configuration writes
*	
*	This file can configure the sensor to send a test image to the Blackfin.
*	This can be done by uncommenting "#define TEST" in micron.h
