Notes: 1.
2. RES may be LOW or HIGH before VDD1 goes HIGH.
3. If Tw(RES) is longer than 500ns (typical) a reset may be generated.
4. All timing values are valid within the operating supply voltage and ambient temperature ranges and referenced to VIL and VIH with
an input voltage swing of VSS to VDD
5. The rise and fall times specified here refer to the driver device and are part of general Hs-mode specification.
6. The device inputs SDA and SCL are filtered and will reject any spike on the bus-lines of with TSW
7. Cb is the capacitive load for each bus line.
8. TH5 is the time from the previous SCLK positive edge to the negative edge of SCE
9. For bus line loads Cb between 100 and 400pF the timing parameters must be linearly interpolated
10.CVLCD is the filtering capacitor on VLCDOUT
11.If Tw(RES) is shorter than max. value a reset pulse is rejected.
