Note:
The value in the left hand column shows the formula used to calculate the timing minimum or maximum from the oscillator clock period.
The value in the right hand two columns shows the timing minimum and maximum for an internal clock at 24MHz (INTCLK).
Measurement points are V_IH for positive pulses and V_IL 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 7is divided by 2;
Crystal Oscillator Clock period x PLL factor when the PLL is enabled.
