[−][src]Constant rubidium::BG2_REF_POINT
pub const BG2_REF_POINT: WriteOnlyVolAddr<[i32; 2]>;
"Background 2 Reference Point" (Affine/Bitmap mode only).
Given in [x, y]
.
Each coordinate is a signed fixed-point value:
- 8 fraction bits
- 19 integer bits
- sign bit
This adds up to less than 32 bits used, but you can just write a normal
i32
value and it'll ignore the high bits and "wrap" into the correct
range.
