VCOM Adjustment and Multiple-Time Programmable Memory
Control. CTL sets the internal DAC code and programs the
MTP memory. A pulse-control method is used to adjust the
VCOM level. See the VCOM Adjustment (CTL) section. To
program the DAC setting into the MTP memory as the power-
on default, drive CTL to the MTP programming voltage using
the correct timing and voltage ramp rates. See the MTP
Programming (CTL) section.
No Connection. Not internally connected.
Exposed Pad. The exposed pad must be connected to GND.
