MIPI I3CSM slave interface
The LPS22DF interface includes an MIPI I3CSM SDR only slave interface (compliant with release 1.1 of the
specification) with MIPI I3CSM SDR embedded features:
•
CCC command
•
Direct CCC communication (SET and GET)
•
Broadcast CCC communication
•
Private communications
•
Private read and write for single byte
•
Multiple read and write
•
In-Band Interrupt request
•
Slave reset pattern
•
Group address
•
Full range VDD IO support
•
Asynchronous modes 0 and 1
•
Synchronous mode
•
Error Detection and Recovery Methods (S0-S6)
In order to disable the I3C block, I2C_I3C_DIS = 1 must be written in IF_CTRL (0Eh).
