STANDARD TIMER TIMING TABLE
(V
unless otherwise specified)
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 V
(1) Formula guaranteed by design.
Legend:
Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;
Psc = Standard Timer Prescaler Register content (STP): from 0 to 255
Cnt = Standard Timer Counter Registers content (STH,STL): from 0 to 65535
