Window Address Function

The window address function enables writing display data consecutively in a rectangular area (a window address area) made in the internal RAM. The window address area is described by the horizontal address register (start: HSA7-0, end: HEA7-0 bits) and the vertical address register (start: VSA8-0, end: VEA8-0 bits). The AM and ID bits set the transition direction of RAM address (either increment or decrement, horizontal or vertical, respectively). Setting these bits enables the R61509V to write data including image data consecutively without taking the data wrap position into account.

The window address area must be made within the GRAM address map area. Also, the AD16-0 bits (RAM address set register) must be set to an address within the window address area.
