Power Control3 (R102h)

Note: True values of PSON and PON are not read when instruction read is executed.

PON, PSON: Turn power supply ON. PON and PSON must be written to power supply ON and start the
internal power supply operation. Follow power supply sequencer to set PON and PSON bits.

VCMR: Selects either external resistance (VCOMR pin) or internal electronic volume (VCM[4:0]) to set
the electrical potential of VCOMH. The internal electronic volume is set by VCM bits

VRH[3:0]: Sets the factor to generate VREG1OUT.

Note: Write VC and VRH bits so that VREG1OUT ≤ DDVDH-

0.5V.
