10. When Xin is driven from an external clock source.
12. All outputs loaded as perTable 9 below.
13. Probes are placed on the pins and measurements are acquired at 1.5V for 3.3V signals (see test and measurement set-up section of this data sheet).
14. Measured between 0.2V
15. This measurement is applicable with Spread ON or Spread OFF.
16. Measured at crossing point (Vx) or where subtraction of CLK–CLK# crosses 0V Measured from V
17. Measured from V
18. Determined as a fraction of 2*(Trise–Tfall)/ (Trise+Tfall).
19. Test load is Rta = 33.2Ω, Rd = 49.9Ω.
11. This is required for the duty cycle on the REF clock out to be as specified. The device will operate reliably with input duty cycles up to 30/70 but the REF clock

5. Multiple Supplies: The Voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
6. Inom refers to the expected current based on the configuration of the device.
7. All outputs loaded as per maximum capacitive load table.
8. Absolute value = ((Programmed CPU Iref) × (2)) + 10 mA.
9. This parameter is measured as an average over 1 µs duration, with a crystal center frequency of 14.31818 MHz.
