Description
Access Unit Select
Select access unit of VRAM. This bit is enabled when
ROT = 1 (rotate the display). When ROT = 0, 16-burst
memory read operation is carried out whatever the
AU setting is.
00: 4-burst
01: 8-burst
10: 16-burst
11: 32-burst
Notes: 1. Above burst lengths are used for 32-bit
Reserved
These bits are always read as 0. The write value
should always be 0.
2. When displaying a rotated image, the
bus. For 16-bit bus, the burst lengths are
twice the lengths of 32-bit bus.
burst length is limited depending on the
number of column address bits and bus
width of connected SDRAM. For details,
see tables 26.3 and 26.4.
