RF Mouse Rx Controller
6.1.5.11 Read Data (EB)
This command is executed in either remote or stream mode. The data is transmitted
even if there has been no movement since the last report or the button status is
unchanged. Following a Read Data command, the registers are cleared after a data
transmission.
6.1.5.12 Set Stream Mode (EA)
This command sets eKM6211 in stream mode.
6.1.5.13 Status Request (E9)
When this command is issued by the system, eKM6211 responds with a 3-byte status
report as follows:

6.1.5.15 Set Auto-speed (E7)
At the end of a sample interval in the stream mode, the current X and Y data values are
converted new values. The sign bits are not involved in this conversion. The
conversion is only in stream mode. The relationship between the input and output
count follows:
