6

SDO

0 ~ VDDV digital output, provide the internal control of the register serial back to read function

7

SDI

Serial data input. 0 ~ VDD V digital input. The pins for the 4 wire serial data serial data flow bus.

8

SCLK

A serial clock input. 0 ~ VDDV digital input. The pins provides the 4 wire serial data clock function

9

nSEL

Serial interface choice input pins. 0 ~ VDDV digital input. The pins for the 4 wire serial data bus provides the choice/make can function, this signal is used to indicate a read/write mode
