 		 #116990 - re flag
Responding to: ???'s previous message
in the ISR
if flag: ERROR <- why error? 1)
old = new
new = capture
flag = true <- why flag is true?? it is not true, it is made true

in main
if flag: new-old = diff
flag = false <-why? 2)

re 'flag'

flag marks that a value is available
in the main the flag is reset when the value has been processes
if the ISR is entered and the flag is still set, the main did not process the values in time
