The SPI interface is a full duplex 4 wire interface and the connection between the MCU and SCP1000 is achieved using MOSI, MISO, SCK and CSB. The I2C interface is slave-only half duplex two-wire interface available on SDA and SCL pins. Interface Options The SCP1000 Pressure sensor has 4 normal operation modes plus power down mode.
