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 24MHz, with minimum and
maximum prescaler value and minimum and maximum counter value.
Measurement points are V
(1) On this product STIN is not available as Alternate Function but it is internally connected to a precise clock source directly derived from the
crystal oscillator. Refer to RCCU chapter for details about clock distribution.
Legend:
Tck = INTCLK period = Crystal Oscillator Clock period when CLOCK1 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
