Potentiometer (VR101) & Toggle Switches (SW101, SW102)
The Evaluation Board has a potentiometer (VR101) and toggle switches (SW101 and SW102). The
potentiometer (VR101) is connected to the CNA21 and uses it to indicate the amount of rotation and direction
of rotation. The toggle switch (SW101) is connected to the CNA21 and uses it to indicate the start/stop of
rotation. Toggle switch (SW102) is connected to CNA33 and used it to reset errors.
The evaluation board also has a through-hole for external controller connector (CN_VOL) and the test points
for verification (TP_VOL), allowing connection of trigger switches and other devices.
The jumper pins (JP103, JP101, JP102) allow you to select whether to use the potentiometer (VR101) and
toggle switches (SW101, SW102) on the board or CN_VOL.
If 1-2 of JP103 are shorted, the potentiometer (VR101) side is valid, and if 2-3 are shorted, the CN_VOL side
is valid.
If 2-3 of JP101 and JP102 are shorted, the toggle switch (SW101 and SW102) side is valid, and if 1-2 are
shorted, the CN_VOL side is valid.

LED
The Evaluation Board has 7 LEDs, 6 of which can be used as the program debugging and system display.
Each LED turns on when the output on the corresponding port is low-level and turns off when the output is
high-level. The Evaluation Board also has through-holes for the CN_LED connector and test points (TP_LED)
to confirm the MCU output.
