Voltage Supply
R
an overflow occurs. If the mouse moves continuously, the 33-bit transmissions repeat
every 50 ms or so.
The L and R fields in the status byte indicate Left and Right button presses. A ‘1’ indicates
that the associated mouse button is being pressed.
The following site contains additional information on interfacing to a PS/2-style mouse:

Voltage Supply
Most modern keyboards and mice work equally well from a 3.3V or 5V supply. The voltage
located immediately above the PS/2 connector along the right edge. The 3.3V setting is
preferred as the FPGA’s output signals operate from the 3.3V supply. The JP2 jumper
should be positioned as shown in Table 6-5 by default.

JP2
Some older keyboards and mice are 5V only. Consequently, the JP2 jumper should be set
for 5V operation as shown in Table 6-5 . The Spartan-3 FPGA can tolerate 5V signals due to
the 270 Ω series resistors on the PS/2 data and clock signals connected to the FPGA. See the
schematic in Figure A-7 for more details.
