When placing the I2Cm module, it states it will setup the pins you select in
the properties window, however when you look at the pin properties window
you will see the pin set for STDCPU, HiZ. But if you look at the pin setting
property selection there is a I2C SDA and I2C SCL choice, so it is confusing,
accept the module setup of STDCPU or use the I2C SDA/SCL choices.
Quick answer is stay with module setup of STDCPU, HiZ. The I2Cm module
is making the correct choice. The I2C SDA/SCL settings are for the I2CHW
This confusion will be cleared up in a future release.
