/*		H2ocon_init.c

	This is a short initialization file the the H2O controller CF2.
	Its primary purpose is to initialize the CF2 pins and peripheral
	chips.  Most importantly, the program shuts down the DC/DC converters
	that power the cameras and current meter.  This is important since
	the controller won't boot if the converters draw more than the current
	limit of 0.5A.
	
	This program should be compiled and the file H2ocon_init.APP stored
	in the CF2 flash using Motocross.  Execute the command "BOOT APP" to
	force the CF2 to always boot this program before starting PicoDOS.
