C5H
-Set VCOMH Voltage
-Select the VCOMH value
-If this register not using the register need be reserved.
-The deviation value of VCOMH between with Measurement and Specification:
-The deviation value of VCOMAC between with Measurement and Specification:
-The nVM need be used in 1
- When nVM=0, the value of VMH[6:0] is from NV memory. So it must program the NV memory first.
- When nVM=1, the vaule of VMH[6:0] is from $C5 register. It can fine-tune the display performance to the best quality
