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
µs or 10 MCLK cycle times.
