definition Type Function
VDI DO Valid data indicator
VDD S Positive power supply
SDI DI SPI data input
SCK DI SPI clock input
nSEL DI Chip select (active low)
FFIT/SDO DO FIFO fill interrupt(active low) or status read data output
nRES DO Reset output（active low）
GND S Power ground
nIRQ DO Interrupts request output（active low）
DATA/nFFS DO/DI Data input(non FIFO mode)/ FIFO select

Clock output (no FIFO )/ external filter capacitor(analog mode)/ FIFO
interrupts(active high)when FIFO level set to 1, FIFO empty
interruption can be achieved
CLK DO Clock output for external microcontroller
