Hex Code Command
Description
F0
Set remote mode
This command sets the remote mode. Data values are reported only in response to
a Read Data command.
EE
Set wrap mode
This command sets the wrap mode. This mode remains until hex FF or hex EC is
received.
EC
Reset wrap mode This command resets the wrap mode
This command requests that all data defined in the data packet format be transmit-
ted. This command is executed in either remote or stream mode. The data is trans-

Read data
mitted even if there has been no movement since the last report or the switch status
is unchanged. Following a Read Data command, the accumulators are cleared af-
ter a data transmission.
EA
Set stream mode This command sets the stream mode
When this command is issued by the system, the mouse responds with a 3-byte
status report as follows:

Scaling is used to provide a course/fine tracking response. At the end of a sample
interval in the stream mode, the current X and Y data values are converted to new
values. The sign bits are not involved in this conversion. 2:1 scaling is only per-
formed in stream mode. In response to a Read Data command, the mouse will
transmit the current value before conversion.
