This instruction returns TILECFG and TILEDATA to the INIT state.

Any attempt to execute the TILERELEASE instruction inside an Intel TSX transaction will result in a transaction abort.

## Operation ¶

    zero_all_tile_data()
    tilecfg := 0// equivalent to 64B of zeros
    TILES_CONFIGURED := 0

## Intel C/C++ Compiler Intrinsic Equivalent ¶

    TILERELEASE void _tile_release(void);

## Flags Affected ¶

None.
