EXTERNAL INTERRUPT TIMING
(Rising or falling edge mode; V
Note: The value in the left hand two columns shows the formula used to calculate the minimum or maximum timing from the oscillator clock
period, prescale value and number of wait cycles inserted. The value in the rignt hand two columns shows the minimum and maximum for
an external clock at 24 MHz divided by 2, prescale value of zero and zero wait status.
