Hi all,
I am trying to determine the specifications on the MPU9250 for SPI communication, as the technical documentation from InvenSense is unclear.
In particular, the InvenSense website says the following about the MPU9250 spi communication:
– "1MHz SPI serial interface for communicating with all registers"
– "20MHz SPI serial interface for reading sensor and interrupt registers"
To me, this means that 20MHz can be used to read not only register 0x3A (interrupt status register), but also sensor registers (is this correct?).
My question is: what other registers (besides 0x3A) can be read at the 20MHz frequency. More specifically, what registers are considered to be the "sensor registers"?
Thank you,
Matt
