	Refer to the 'max. time interval to update data' comment
	in function i8082_Init. The period to update every channel 
	of each 8082 must be less than the max. interval listed 
	in i8082_Init.
	
	This function is not necessary. 
	1. If your program calls i8082_ReadFreq at period less than the 
	   max. time interval, then you don't need to call the function.
	2. If your program calls i8082_ReadFreq at a random period,
	   then you must call i8082_AutoScan.
