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 25MHz, and minimum

prescaler factor (=2).

Measurement points are taken with reference to VIH-VIH for positive pulse and VIL-VIL for negative pulse

(1) Formula guaranteed by design.

Legend:

Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;

2 x OSCIN period when OSCIN is divided by 2;

OSCIN period x PLL factor when the PLL is enabled.

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