TJA1051T/3 internal pull down resistor on pin S

Hi all,

 

I am currently dealing with the CAN transceiver TJA1051T/3. It has pin named S which is used to bring the transceiver in Normal or Silent mode. I am not sure if I am correct but I think the transceiver should stay Silent until the MCU activates it by setting pin S low. However, S pin has internal pull down resistor which brings it in Normal mode by default. Since the MCU I am using has no pull up or pull down enabled in the first place, it will allow internal pull down to dominate.

My question is what is the value of the internal pull down resistor inside the S pin of the TJA1051T/3?
