Function
Formal Name Definition
1 WAKE Input Wake
This input pin controls the device mode.
2 RSTB Input Reset
This input pin is used to initialize the device configuration and fault registers,
as well as drive the device into a low-current Sleep mode.
3 CSB Input Chip Select
(Active Low)
This input pin is connected to a chip select output of a master microcontroller
(MCU).
4 SCLK Input Serial Clock
This input pin is connected to the MCU providing the required bit shift clock for
SPI communication.
5 SI Input Serial Input
This pin is a command data input pin connected to the SPI Serial Data Output
of the MCU or to the SO pin of the previous device of a daisy
-chain of devices.
6 VDD Power Digital Drain Voltage
This pin is an external voltage input pin used to supply power interfaces to the
SPI bus.
7 SO Output Serial Output
This output pin is connected to the SPI Serial Data Input pin of the MCU or to
the SI pin of the next device of a daisy
-chain of devices.
