How to set Canbus Standby Pin

Hello,

I am trying to configure the TJA1044 STB pin to HIGH to enter standby mode. But, I cannot figure out how to configure this pin.

Schema of TJA1044 and LPC55s06 connection given below. How can I set to HIGH instead of LOW to STB pin of TJA1044?

By connecting the "top" of R29 (the wire to STB on the CAN transceiver) to +3.3V ?
There is no GPIO connected to that if thats what you are asking, according to the schematics..

Hello justsomeonelse,

You can do some overwork with this board, connect STB to a gpio of lpc55s06 to control.
