    I am working on CAN1 module & would like to configure out its GPIO as input & output. I have following confusion. 


In Special cases of IBE and OBE of excel sheet of MPC5748G, it is written as


CAN_TX pin "always ON"



So, Is it menas, There is no need to configure CAN_TX pin because it is always ON?


Now below shown configurations are taken from Excel sheet of MPC5748G, It states that for there is need to write value 6 in Source signal select and Also IMCR value as[701-512] which is also 6 in input muxing table. 


Can you please guide me how I can configure these two pins to work CAN_1 good? Special cases are confusing me? In which situation I need to take care about special case?
