6.8. Voltage Reference (VREF) and Analog Ground Connectors (J13 and J14)
The VREF connector can be used to connect the VREF pin from the MCU (P0.0) to external 0.1 uF and 4.7 uF
decoupling capacitors. The C8051F700 device is connected to the capacitors through the J13 header. The AGND
pin from the MCU (P0.1) can be connected to the board digital ground through the J14 header.
6.9. Potentiometer (J16)
The C8051F700 device has the option to connect port pin P1.2 to a 10 k linear potentiometer. The potentiometer
is connected through the J16 header. The potentiometer can be used for testing the analog-to-digital (ADC)
converter of the MCU.
6.10. C2 Pin Sharing
On the C8051F700, the debug pin C2CK is shared with the /RST pin. The target board includes the resistor
necessary to enable pin sharing which allows the pin–shared /RST to be used normally while simultaneously
debugging the device. See Application Note “AN124: Pin Sharing Techniques for the C2 Interface” at
www.silabs.com
for more information regarding pin sharing.
