Note: The value in the left hand column shows the formula used to calculate the timing minimum or maximum from the oscillator clock period,

standard timer prescaler and counter programmed values.

The value in the right hand two columns show the timing minimum and maximum for an internal clock (INTCLK) at 24MHz, and minimum

prescaler factor (=2).

Measurement points are VIH for positive pulses and VIL for negative pulses.

Legend:

Tck = INTCLK period = Crystal Oscillator Clock period when CLOCK1 is not divided by 2;

2 x Crystal Oscillator Clock period when CLOCK1 is divided by 2;

Crystal Oscillator Clock period x PLL factor when the PLL is enabled.

Prsc = Precsaler factor defined by Extended Function Timer Clock Control bits (CC1,CC0) on control register CR2 (values: 2,4,8).
