Field Name             Bits   Default   Description
DEPTHPITCH             13:2   0x0       Z buffer pitch in multiples of 4 pixels.
DEPTHMACROTILE         16     0x0       Specifies whether Z buffer is macro-tiled. macro-tiles are
                                        2K aligned
                                        POSSIBLE VALUES:
                                        00 - macro tiling disabled
                                        01 - macro tiling enabled
DEPTHMICROTILE         18:17  0x0       Specifies whether Z buffer is micro-tiled. micro-tiles is
                                        32 bytes
                                        POSSIBLE VALUES:
                                        00 - 32 byte cache line is linear
                                        01 - 32 byte cache line is tiled
                                        02 - 32 byte cache line is tiled square (only applies to 16-bit pixels)
                                        03 - Reserved
DEPTHENDIAN            20:19  0x0       Specifies endian control for the Z buffer.
                                        POSSIBLE VALUES:
                                        00 - No swap
                                        01 - Word swap
                                        02 - Dword swap
                                        03 - Half Dword swap
