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.

(1) n = 1 if the input is rising OR falling edge sensitive

n = 3 if the input is rising AND falling edge sensitive

(2) In Autodiscrimination mode

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.
