Reset Timing:** **Figure 2 Reset Timing** VDDI=1.65 to 3.6V, VDD=2.4 to 3.6V, AGND=DGND=0V, Ta=25 โ„ƒ ## Notes: 1. The reset cancel includes also required time for loading ID bytes, VCOM setting and other settings from NVM (or similar device) to registers. This loading is done every time when there is HW reset cancel time (tRT) within 5 ms after a rising edge of RESX. 2. Spike due to an electrostatic discharge on RESXline does not cause irregular system reset according to the table below: 3. During the Resetting period, the display will be blanked (The display is entering blanking sequence, which maximum time is 120 ms, when Reset Starts in Sleep Out โ€“mode. The display remains the blank state in Sleep In โ€“mode.) and then return to Default condition for Hardware Reset. 4. Spike Rejection also applies during a valid reset pulse as shown below: Page 9 of 14 ## **ical Characteristics Opt** |**Item**|**Item**|**Symbol**
