37.2.11.2.1 Target Reset Pattern Received After RSTACT CCC
This is the normal and preferred method of configuring and taking reset action.
The Controller typically sends the Target Reset
Action CCC with an appropriate defining byte to configure the
Target to take a particular reset action (or to not take any action). The
user software is recommended to read the defining byte from the I3CxRSTACT register and prepare the firmware to act
accordingly when the next Target Reset Pattern is received. The Target sets
the RSTDET bit and the I3CxRIF interrupt flag to notify the user
when a Target Reset Pattern is received. Refer to Levels of Target
Reset for more details.
Important: The Controller typically sends the
Target Reset Pattern in the same frame as RSTACT CCC, separated by a
Restart. However, if the Controller begins a new frame using a Start
condition instead, the MIPI I3C® Specification recommends clearing
the reset action that was configured earlier.
