; This is the ADC cal routine.This routine is programmed into 
; reserved memory by the factory. 0xAAAA and 0xBBBB are place- 
; holders for calibration data.  
;The actual values programmed by TI are device specific. 
;
; This function assumes that the clocks have been
; enabled to the ADC module.
