Notes:

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

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 is the greater of 5 s or 10 MCLK cycle times.
