ST92F120 - ELECTRICAL CHARACTERISTICS
EXTERNAL INTERRUPT 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.
The value in the right hand two columns shows the timing minimum and maximum for an internal clock at 24MHz (INTCLK).
Measurement points are V
(1) Formula guaranteed by design.
Legend:
Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;
