7.10.2. Case 2 – RESX Line is Held Low by Host at Power On
If RESX line is held Low (and stable) by the host during Power On, then the RESX must be held low for minimum 10 µ sec after both VDD
and VDDIO have been applied.
7.10.3. Uncontrolled Power Off
The uncontrolled power off means a situation when e.g. there is removed a battery without the controlled power off sequence. There will not
be any damages for the display module or the display module will not cause any damages for the host or lines of the interface.
At an uncontrolled power off the display will go blank and there will not be any visible effects within (TBD) second on the display (blank
display) and remains blank until “Power On Sequence” powers it up.

Time when the latter signal rises up to 90% of its Typical Value.
e.g. When VDD2 comes later, This time is defined at the cross point
