Description

CS Input Chip Select.This active LOW input activates the device.When HIGH, the device enters low-power standby mode, ignores other inputs, and the output is tristated.When LOW, the device internally activates the SCK signal.A falling edge on CS must occur before every opcode.SCK SI[1] SO[1] Input Input Output Serial Clock.All I/O activity is synchronized to the serial clock.Inputs are latched on the rising edge and outputs occur on the falling edge.Because the device is synchrono
