In the figure below, the system processor is an SPI master to the MPU-6000. Pins 8, 9, 23, and 24 are used
to support the /CS, SDO, SCLK, and SDI signals for SPI communications. Because these SPI pins are
shared with the I
through the interface bypass multiplexer, which connects the processor I
interface pins.
Since the MPU-6000 has limited capabilities as an I
manage the initial configuration of any auxiliary sensors, another method must be used for programming the
sensors on the auxiliary sensor I
When using SPI communications between the MPU-6000 and the system processor, configuration of
devices on the I
device and register on the auxiliary I
external sensors are configured, the MPU-6000 has the capability to perform single or multi-byte reads using
the sensor I
well as to the sensor registers.
