C/SPI interface.
shows the sensor circuit.
• The sensor is powered by the P1V8_3V3_BRD rail.
• Discrete pull-up resistors for the I
2
C bus lines are provided.
• Default address is configured as 0x1F:
— Address can be changed by pull-up/pull-down resistors on SA0 and SA1 lines.
• There is one interrupt signal routed to PTA19 pin of KW36.
• The I
