16.4 Control Registers

16.4.1 LCD Screen Starting Address Register

The LCD screen starting address register (LSSA) is used to inform the starting address of current display buffer. Different

LCD frames can be switched quickly by simply modifying content of LSSA. The LCD controller will start fetching pixel data

from system memory at this address.

16.4.2 LCD Virtual Page Width Register

The LCD virtual page width register (LVPW) contains the width of a virtual screen that may be wider than real setting. This

field is used for calculating the starting point of next line.

16.4.3 LCD Screen Width Register

The LCD screen width register (LXMAX) is used to specify the width of the LCD panel in pixels. Every bit of display data

maps to one pixel of LCD panel. LXMAX represents number of data in byte of each line.
