| 0: disable, 1: enable |

| 0: disable, 1: enable |
| (Note that this function has the functionality of bit 1 even when |
| bit 1 is not set. However, the format is different from that of bit 1. |
| In addition, when bit 1 and bit 2 are set at the same time, bit 2 will |
| override bit 1.) |

| 0: disable, 1: enable |
| (Note that this function has the functionality of bit 1 even when |
| bit 1 is not set. However, the format is different from that of bit 1. |
| In addition, when bit 1, bit 2 and bit 3 are set at the same time, |
| bit 3 will override bit 1 and 2.) |

| 0: disable, 1: enable |
| (Note that the absolute/relative coordinate output still depends on |
| bit 2 and 3. That is, if any of those bit is 1, host will receive |
| absolute coordinates; otherwise, host only receives packets with |
| relative coordinate.) |
