Function

Output Low power mode control signal output pin (for power supply IC).

This pin connects to LPM pin of power supply IC.

Output DC/DC converter ON/OFF signal pin for power supply IC.

This pin connects DCON pin of power supply IC.

Output Regulator ON/OFF control signal pin for power supply IC.

This pin connects to RGONP pin of power supply IC.

Output Control signal to select x4/x5/x6/x7 booster of power supply IC for VDD1.

Connect to the VCD11 and VCD12 pins of the power supply IC.

Output Control signal to select x2/x3 booster of power supply IC for VDD2.

Connect to the VCD2 pin of the power supply IC.

Output Signal for selecting the level of the power supply IC booster voltage, to be

used for the maximum voltage of VO. Selects that the booster voltage level

is either the same level as VDD1 or a multiple of minus 1.

connection

Output This pin is the center rectangle signal output (Vp-p) for common modulation

between 0 V and VDD2.

Input This is an external-power supply input pin for VCOM.

This pin is valid when BGRS (power supply control register 1: R25) = 1. In

this case, the reference voltage of the amplifier for setting the common

waveform center value is input from outside the µPD161623.

When BGRS = 0, the µPD161623 internal voltage is set as the reference

voltage of the amplifier for setting the common waveform center value. In

this case, leave it open.

Input This pin connects an external feedback resistor for setting VCOM.

This pin is valid when FBRSEL = L. In this case, connect a feedback resistor

between the VCOM pin and GND.

When FBRSEL = H, the amplifier for setting the common waveform center

value operates as a voltage follower. In this case, leave it open.
