ST92141 - ELECTRICAL CHARACTERISTICS
EXTENDED FUNCTION 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 25MHz, and minimum
prescaler factor (=2).
Measurement points are taken with reference to V
(1) Formula guaranteed by design.
Legend:
Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;
Prsc = Prescaler factor defined by Extended Function Timer Clock Control bits (CC1,CC0) on control register CR2 (values: 2,4,8).
