Notes:

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

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

10 k

Ω per device.

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