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, with minimum and

maximum prescaler value and minimum and maximum counter value.

Measurement points are taken with reference to VIH-VIH / VOH-VOH for positive pulse and VIL-VIL / VOL-VOL 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.

Psc = Standard Timer Prescaler Register content (STP): from 0 to 255

Cnt = Standard Timer Counter Registers content (STH,STL): from 0 to 65535

TSTIN = Standard Timer Input signal period (STIN).
