Description

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.

7, 11

NC

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.
