Window Address Function
The window address function enables consecutive data write within the rectangular window-address area
on the on-chip GRAM, which is specified with horizontal address registers (start: HSA7-0, end: HEA 7-0)
and vertical address registers (start: VSA7-0, end: VEA7-0).
The address transition direction is determined with AM bits (either increment or decrement). Accordingly,
the data, including picture data, are written consecutively without taking the data wrap position into
consideration.
The window-address range must be specified within the GRAM address area. An address set must be set
within the window-address range.

Note: In high-speed RAM write mode, the lower two bits of the address must be set as follows.
ID0
=
0: The lower two bits of the address must be set to 11.
ID0
=
1: The lower two bits of the address must be set to 00.
