What pin settings do I need to make for the I2C on SCI in SSP?

Question:

What pin settings do I need to make when using an I2C on the SCI peripheral in SSP?

Answer:

Over and above the settings for the pin locations on the MCU the pin type needs to be set as well. For example, when using the Simple I2C you need to set the output type of SDA and SCL to n-channel open drain. Additionally, make sure an external pull-up is available on these lines.
