TMS570LC4357: Clarification required on how CAN selection between the functional and GIO modes is achieved.

Hello,

I am using the TMS570LC4357 and I have a question on the selection between functional mode and the GIO mode of the CAN module.
In the Technical Reference Manual TMS570LC43x 16/32-Bit RISC Flash Microcontroller (SPNU563A March 2018) section 27.17.34 CAN TX IO Control Register (DCAN TIOC)
Bit 3 Func has the following text:
    CAN_TX function. This bit changes the function of the CAN_TX pin.
    0 CAN_TX pin is in GIO mode.
    1 CAN_TX pin is in functional mode (as an output to transmit CAN data).
    Forced to 1, if Init bit of CAN control register is reset.
    
What does the final sentence "Forced to 1, if Init bit of CAN control register is reset." actually mean in practice?

Does it mean that if the Init bit of CAN control register is reset then the CAN module is forced to the functional mode even if it was initialised to the GIO mode?

Does it mean that if I want to operate the CAN in GIO mode then the Init bit of CAN control register has to be permanently set?

Thank you.
