TQM5200 I2C Second bus

[Jani.Sarkijarvi at elektrobit.com]

It is very possible that, setting are not right. I found from mpc5200 manual this register: (MBAR + 0x0B00, GPS, GPIO Standard registers). Where should be right place to modify those register?

BR,

Is your "GPS Port Configuration Register" setting correct?
