I am using MC33905S for my application, as power regulator and CAN transceiver, in Normal mode and is working fine so far. However, I can't make the I/O-3 to drive a small LED.
What I have done is, during Initializing the LIN and I/O I set the LIN_T2, LIN_T2 bits to '10' for 'pin operation as I/O: HS switch and Wake-up input'
And when in Normal mode I set the I/O register I/O-3 , I/O-3  to '11' for 'I/O-3 HS driver enable' which should bring the I/O-3 pin to Vsup2 voltage and drive my LED ... but it doesn't.
Can anyone point-out what did I missed? I can control I/O-0 and I/O-1 just fine but not I/O-3.
