MULTIFUNCTION TIMER EXTERNAL TIMING TABLE
(V
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) 3.0 - 4.0V voltage range is only available on devices with suffix L or V, with different frequency limitatio ns (L: 8 MHz, V: 16 MHz)
(2) n = 1 if the input is rising OR falling edge sensitive
(3) In Autodiscrimination mode
Legend:
Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;
