Programmable Registers
33.4.3 LCDIF General Control2 Register (HW_LCDIF_CTRL2)
The LCDIF Control Register provides overall control of the LCDIF block.
HW_LCDIF_CTRL2: 0x020
HW_LCDIF_CTRL2_SET: 0x024
HW_LCDIF_CTRL2_CLR: 0x028
HW_LCDIF_CTRL2_TOG: 0x02C
The LCDIF Control2 Register provides additional programming to the LCDIF. It implements
some bits which are unlikely to change often in a particular application.
