;Input the frequency of operation of the device in the in MHz (c      15MHz
;Then choose Save as from the file menu and then save formatted text file.
;Type in the Filename TIMINGS.H and save it in the include subdir in the flash tools directory.
;Resulting cycle time:                                          66.66667nsec
;(When typing the filename in the dialog box use quotes, else Excel sometimes puts in an extension !)
; Note:      You must still select the clock input and PLL prescale constant in VAR.H to
;            generate this clock frequency.
