Note: The value left hand two columns show the formula used to calculate the timing minimum or maximum from the oscillator clock period,

prescale value and number of wait cycles inserted.

The value right hand two columns show the timing minimum and maximum for an external clock at 24 MHz divided by 2, prescale value of zero

and zero wait status.
