[][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.
