Potentiometer in Parallel with Cmod Selection Jumper (JP1, JP2)
Figure 3-4. Potentiometer in Parallel with Cmod Selection Jumper
If potentiometer RV2 is needed for the left channel, put shunts on JP1. If potentiometer RV3 is
needed for the right channel, put shunts on JP2.
PSoC VCC Selection Jumper (JP3)
Figure 3-5. PSoC VCC Selection Jumper
Place shunts on pin 2 and pin 3 of JP3 to select fixed 5V as the PSoC VCC power supply. Place
shunts on pin 1 and pin 1 of JP3 to select variable Vadj as the PSoC VCC power supply. If VCC
power is applied, the power on LED D2 lights up. Refer to
more information.
XRES/INT Selection Jumper (JP4)
Figure 3-6. XRES/INT Selection Jumper
Pin 3 of J3 can serve as the XRES signal or INT signal. If it is the XRES signal, put shunts on pin 1
and pin 2 of JP4. If it is the INT signal, put shunts on pin 2 and pin 3 of JP4. The default setting of
JP4 is shorting pin 1 and pin 2.
External 9V Battery Power Connector (BH1)
The board supports a 9V battery power supply. The 9V battery plugs on this connector directly to
power the board.
