Si10xx-DK
10.10. IREF Connector (J7)
The Si1000 Motherboard also features a current-to-voltage 1 k load resistor that may be connected to the current
reference (IREF0) output that can be enabled on port pin (P0.7). Install a shorting block on J7 to connect port pin
P0.7 of the target device to the load resistor. If enabled by software, the IREF0 signal is then routed to the J2[8]
and H1[2] connectors.
10.11. VREF and AGND Connector (J13, J14)
The Si1000 Motherboard also features 4.7 µF capacitor in parallel with a 0.1 µF that can be connected to P0.0/
VREF when using the Precision Voltage Reference. The capacitors are connected to P0.0/VREF when a shorting
block is installed on J13. Using the Precision Voltage Reference is optional since Si10xx devices have an on-chip
High-Speed Voltage Reference.
The shorting block J14 allows P0.1/AGND to be connected to ground. This provides a noise-free ground reference
to the analog-to-digital Converter. The use of this dedicated analog ground is optional.
10.12. C2 Pin Sharing
On the Si10xx, the debug pins C2CK and C2D are shared with the pins RST and P2.7, respectively. The target
board includes the resistors necessary to enable pin sharing which allow the RST and P2.7 pins 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.
