When enabled, the hardware automatically drives the pin low while the controller is active and high when it enters Sleep mode, allowing automatic standby control of an external CAN transceiver without software intervention. This series adds driver support for the XSTBYEN-based transceiver standby control feature. Tested on QCS6490 RB3 Gen2 with a PCAN-USB FD adapter: the transceiver is active in normal mode, CAN communication works correctly, and the pin is automatically managed across sleep and wake transitions.
