Load tile configuration from a 64-byte memory location specified by "mem_addr". The tile configuration format is specified below, and includes the tile type pallette, the number of bytes per row, and the number of rows. If the specified pallette_id is zero, that signifies the init state for both the tile config and the tile data, and the tiles are zeroed. Any invalid configurations will result in #GP fault.
