(h)CAN bus is the communication bus for load sharing, and also synchronizes signals between the two systems.

(i)TOMBYP is the status of the manual bypass switch on the system frame. When the manual bypass switch turns on, MCU can detect its status via TOMBYP_I(6) and auto-transfer to bypass the mode and its alarm.
