1. The actual value used could vary with tolerance.
2. For highest glass capacitance values, LCD_GCR[LADJ] should be configured as specified in the LCD Controller chapter
within the device's reference manual.
3. VIREG maximum should never be externally driven to any level other than VDD - 0.15 V
4. 2000 pF load LCD, 32 Hz frame frequency
