Report Length: 33 bytes
1. General Incoming Data - Relative Mode
This data is returned when new data is detected such as button presses, unit id change or touch of touchpad. This report can be manually stimulated by sending a Generate Data output report which is very useful for obtaining the initial state of the device immediately after enumeration. Send a Touchpad Mode Change output report to change the way the touchpad reports data; either absolute or relative.

is tapped gently down and up and then held down the value will stay 1 (equivalent
to holding the left mouse button down). This byte would be used for the
tap to click feature if using the touchpad as a mouse.

if the touchpad is to be used as a mouse.

byte 15 is the MSB or high byte and byte 18 is the LSB or low byte.
2. General Incoming Data - Absolute Mode
This data is returned when new data is detected such as button presses, unit id change or touch of touchpad. This report can be manually stimulated by sending a Generate Data output report which is very useful for obtaining the initial state of the device immediately after enumeration.

0 = 1st row, bit 1=2nd row, bit 2=3rd row, bit 3=4th row, bit 4=5th row,
bit 5=6th row. Note the intensities are not affected by this command.

add 32 to the index given in Figure 1. For example to control the lower
left key bank 1 index=5, the corresponding bank 2 is index=37.
State: 0 = off, 1 = on and 2 = flash. Set the frequency of the flash
with output report 12. Set Frequency of Flash.

Save: Any value other than 0 will save the current backlight state to the EEPROM so when the device is replugged it will display this save backlighting. Note because there is a limited number of times the EEProm can be written to, it is not a good idea to do this often.
14. Change PID
Send this output report to change between the two PIDs. This needs to be done only if the user wishes to have the joystick endpoint.

TMode: 3 to have the touchpad send 3 byte relative data (General
Incoming Data-Relative Mode) , 5 to have the touchpad send 5 byte absolute
data (General Incoming Data-Absolute Mode). These values also control how
the touchpad will behave if a native mouse or native joystick are enabled
(bit 3 of FSE is set). If a native mouse is desired then the device must
be in PID #1 with TMode set to 3. If a native joystick is desired then the
device must be in PID #2 with TMode set to either 5 or 7.
FSE: Set bit 1 to flip vertically the touchpad coordinates, this affects
the actual data in the General Incoming Data input reports. This is useful
if the unit it desired to be used upside down with keys on top. Default
0. Set bit 2 to suppress the tap to click feature of the touchpad, applicable
only if native mouse is enabled. Set bit 3 to enable the native mouse if
in PID #1 or the native joystick if in PID #2.
Example: Set touchpad behavior to native mouse with pad in normal orientation, tap to click on. Must be in PID#1.
