• FRMSIZE: Frame Size
In single scan mode, this is the frame size in words. In dual scan mode, this is the size of each panel. If a dual scan config-
uration is selected in LCDCON2 register or bit DMA2DEN in register DMACON is set, the bit DMAUPDT in that same
register must be written after writing any new value to this field in order to make the DMA controller use this new value.
• BRSTLN: Burst Length in words
Program with the desired burst length - 1
