Table 9.17.1 Reset timing 
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 RESX line does not cause irregular system reset according to the table below:   
 

RESX Pulse 

Action 

Shorter than 5us 

Reset Rejected 

Longer than 9us 

Reset 

Between 5us and 9us 

Reset starts 

 
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 –mode. The display remains the blank state in Sleep In -mode.) and then return 
to Default condition for Hardware Reset. 
4. Spike Rejection also applies during a valid reset pulse as shown below: 

 

5. When Reset applied during Sleep In Mode. 
6. When Reset applied during Sleep Out Mode. 
7. It is necessary to wait 5msec after releasing RESX before sending commands. Also Sleep Out command cannot be sent 
for 120msec.
