0 ~ VDDV digital output, provide the internal control of the register serial back to read function
Serial data input. 0 ~ VDD V digital input. The pins for the 4 wire serial data serial data flow bus.
A serial clock input. 0 ~ VDDV digital input. The pins provides the 4 wire serial data clock function
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
Interrupt output pins
Close input pins. 0 ~ VDDV digital input. In addition to shut down all the mode mode SDN = 0. When SDN = 1 chip will be completely shut down and the content of the register will be lost.
