MCF52233 SDA and SCL

[anthonyrios]

I am working communicating with a magnetometer through I2C.  I am pretty confident our code is right for the I2C as far as init, read and write.  We also added external pull up resistors from the data lines to VDD.  We are not getting any clock signal from SCL or data from SDA.  Do these pins need to be configured in some way?

My partner figured it out.  It turns out the

MCF_GPIO_PASPAR = 0X05

This sets the PASPAR1 and PASPAR0 corresponding to SCL and SDA pins to primary function which is needed for the I2C.
