1.12 High Data Rate (HDR) Modes

The I3C module on 8-bit PIC devices does not support HDR modes. However, the module can detect HDR entry and exit patterns to ensure proper device operation. When the controller enters the HDR mode using any ENTHDRx CCCs, the device enters HDR mode (OPMD = 0b1x). In this mode the device ignores all the HDR traffic on the bus until it detects an HDR Exit Pattern. Once the Target detects the HDR Exit Pattern on the bus, it reverts to operating in SDR mode (OPMD = 0b0x).
