2) HVON Flag hold time
Charge-pump starts with HVON Flag = 1.
In automatic charge-pump mode, charge-pump stops automatically after charge-pump rising period (set to control
register 1), and HVON Flag is automatically canceled (HVON Flag = 0.). HVON Flag is used for keeping the
charge-pump voltage.
In manual charge-pump mode, charge-pump is active until canceled of HVON Flag.

3) LE Flag hold time
The image data shift with LE Flag = 1.
When the data finish shifting, LE Flag is automatically canceled.
