- Changed the priority for packet bursts of extended read responses to the lowest priority, so other frames win arbitration (e. g. on the CAN bus) when they are sent. This will help other events moving on the bus.

- Changed functionality for extended page read request with optional byte. If the optional byte is 0, 256 registers will be read now, instead of 1.
