HDR Enter Pattern

When the Controller enters an HDR mode, it has a bus-wide effect and the whole I3C bus is configured in the selected HDR mode. Once entered, the HDR mode remains in effect until the end of the transaction.

To enter an HDR mode, the Controller broadcasts an Enter HDR Mode CCC (ENTHDR1 through ENTHDR8 CCCs). Even though the HDR modes and their corresponding CCCs are not supported by this Target module, the Target module detects when the Controller is entering an HDR mode and ignores all traffic on the bus until it detects an HDR Exit Pattern.
