[−][src]Constant rubidium::BG3_REF_POINT
pub const BG3_REF_POINT: WriteOnlyVolAddr<[i32; 2]>;
"Background 3 Reference Point" (Affine mode only).
Given in [x, y]
.
Each coordinate is a signed fixed-point value:
- 8 fraction bits
- 19 integer bits
- sign bit
You can just write a normal i32
value and it'll simply end up ignoring the
high bits and "wrapping" properly into range.
