;Input the frequency of operation of the device in the in MHz (cell H2)										20	MHz							
;Then choose Save as from the file menu and then save as a tab delimited file. 																		
;Type in the Filename TIMINGS.H and save it in the include subdir in the flash tools directory.																		
;Resulting cycle time:										50	nsec							
;																		
; Note:  			You must still select the clock input and PLL prescale constant in VAR.H to 															
;			generate this clock frequency.
