Electrical Ground. Both analog and digital.
Power Supply Input. Refer to Note 2 in Appendix A
“Schematics and Layouts” . Do not plug in 9V
supply and connect to PICkit? 1 Flash Starter Kit.

—
SPI? Chip Select signal for the external ADCs. Do
not populate both the MCP3551 and the MCP3302
as they share the same CS0 signal.
SCK/SCL

ST
SPI Clock or I 2 C? Clock Signal. Note that external
weak pull-up R 20 connects this signal to V DD2 .
SDI/SDA

ST
SPI Data In or I 2 C Data signal (Data Out on ADC).
Note that external weak pull-up R 14 connects this sig-
nal to V DD2 .

SPI Data Out Signal (Data In on DAC and ADC)
SPI Chip Select Signal for the External DACs. Do not
populate both the MCP492X and the MCP482X as
they share the same CS0 signal.
LDAC

O
—
Latches the DAC Output When Low. Note the weak
pull-down resistor R 5 if the firmware doesn’t drive the
pin to a desired state.
V REF_ADC

I
—
JP4 selects the V REF source to use as the ADC
reference signal. The PICmicro ? microcontroller on
the PICkit? 1 Flash Starter Kit may use this for its
internal ADC’s V REF .
LED0/TX
5
O
—
Active High Red LED Signal. This I/O also has the
USART’s TX signal multiplexed on it.
LED1/RX
4
I/O
—
Active High Green LED Signal. This I/O also has the
USART’s RX signal multiplexed on it.
SW0
3
I
—
S1’s Switch 1. This pin uses the internal pull-up resis-
tor to determine when the switch is open.
SW1
2

—
S1’s Switch 2. This pin uses the internal pull-up resis-
tor to determine when the switch is open.
SW2

I
—
S1’s Switch 3. This pin uses the internal pull-up resis-
tor to determine when the switch is open.
