// Module name: WriteURB.asm
//
// General purpose module to write data to URB using the URB handle/offset in r0
//
//----------------------------------------------------------------
// Assume:
// - a0.0 and a0.1 is meg desc, has been assign with URB offset and msg size
// - MRFs are alrady assigned with data.
//----------------------------------------------------------------
//
// 16x16 byte pixel block can be saved using just 1 "send" instruction.
#if defined(_DEBUG)
mov (1) EntrySignature:w 0x3535:w

// URB write header:
//mov (8) MSGSRC.0:ud r0.0<8;8,1>:ud // Copy parent R0 header
//shr (1) Temp2_W:uw URBOffset:uw 1:w // divide by 2, because URB entry is counted by 512bits. Offset is counted by 256bits.
