1
SCLK
I
Serial Clock. SCLK provides the serial clock for accessing data from the part and writing serial data
to the control registers.
2
DOUT
O
Data Out. The data on this pin represents data being read from the control registers and is clocked
out on the falling edge of the SCLK.
3
DIN
I
Data In. Data written to the control registers is provided on this input and is clocked in on the
rising edge of the SCLK.
4
CS
I
Chip Select, Active Low. This input frames the serial data transfer.
5, 6
DIO0, DIO1 I/O
Multifunction Digital I/O Pins.

No Connect.
8, 10
AUX COM
S
Auxiliary Grounds. Connect to GND for proper operation.
9
RST
I
Reset, Active Low. This input resets the embedded microcontroller to a known state.
