Freescale Semiconductor
Internal operating frequency
Internal clock period (1/f
RST input pulse width low
IRQ interrupt pulse width low (edge-triggered)
IRQ interrupt pulse period
1. V
2. Values are based on characterization results, not tested in production.
3. The minimum period is the number of cycles it takes to execute the interrupt service routine plus 1 t
