Notes:

1. All timing (except Rise and Fall time) is referenced to the 50% level of the waveform. Input test levels are

VIH = VDD – 0.4 V, VIL = 0.4 V. Rise and Fall times are referenced to the 20% and 80% levels of the waveform.

2. The minimum RESET pulse width assumes the SDITHRU pin is tied to ground via a pulldown resistor no greater than

10 kΩ per device.

3. The minimum RESET pulse width is 33/PCLK frequency (i.e. 33/8.192 MHz = 4 µs).
