IRS: Select the resistors for the V0 voltage level adjustment. 1
HD[1..0]: Setup the LCD driving current. Normally big panel use bigger driving current to void bad display
BLK_EN: Blinking. 0
PBK_EN: Whole or Partial Blinking selection. 0

use the internal resistors. The V0 voltage level is regulated by an external resistive voltage divider
that is attached to the VR signal.
blinking area is depending on the scroll window. That means the partial area is setting by register
SWSXR, SWSYR, SWRXR and SWRYR. When the Partial Blinking off, the above four registers had
better clear to 0. Note, only BLK_EN set to “1” when blink is active.
