ST92F124/F150/F250 - ELECTRICAL CHARACTERISTICS
WATCHDOG 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,
watchdog 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
Legend:
Tck = INTCLK period = Crystal Oscillator Clock period when CLOCK1 is not divided by 2;
Psc = Watchdog Prescaler Register content (WDTPR): from 0 to 255
Cnt = Watchdog Couter Registers content (WDTRH,WDTRL): from 0 to 65535
