Floating Window Buffer Memory Start Address Bits [15:0]
These bits determine theword address of the start of Floating Window Buffer Memory for Floating Window
mode. These registers are effective in Floating Window mode only (REG[00h] bit 4, 3 = 1)

These bits determine words per line for Window /Floating Window features. This register is effective in
Window features is selected (REG[00h] bit 4 = 1)
This register must be programmed with a value calculated as follows :
REG [06h ], REG [05h ] = H-----o----r--i--z---o----n---t--a---l--W------i--n---d----o---w----S----i--z---e--(---p----i--x---e---l--s--)- – 1
