0-7
Description
1 = Right button pressed
1 = Middle button pressed
1 = Left button pressed
Reserved
0 = Normal speed, 1 = Autospeed
0 = Disabled, 1 = Enable
0 = Stream mode, 1 = Remote mode

m. Set Resolution (E8, XX)
SC84520 provides four resolutions selected by the second byte of this command as follows:
Second Byte XX

Resolution
8 dots/count
4 dots/count
2 dots/count
1 dot/count
n. Set Autospeed (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:
Input
