Syscall index: 0x0272
Function signature: void Bdisp_AllClr_VRAM(void)
Clears the contents of VRAM with white pixels.\
It’s not suggested you use this syscall to clear VRAM if speed is important. Instead do 32-bit writes as (partially) described in Display. If you will be redrawing the entire display anyway, there is no need to clear VRAM in any case.
