CAN Bus Flow Control on STM32H7

I will use STM32H753 to design the CAN bus circuit.

I saw the CAN TX and RX but couldn't find out the flow control pin.

Some chips call it nSTB or S.

Could you tell me which gpio I can use?

PS: the transeciver I will use is SN65HVD1050-EP

Dear @CKuo.2

You can use any GPIO as Output push-pull to drive STB pin. This signal is not a part of the CAN peripheral.

It's up to the user to manage it.
