 408           Configures the type of the general port B bits.  1 is chip select,
 409           0 is port.  Most products should use 00 here.

 416           Configures the direction of general port B bits. 1 is out, 0 is in.
 417           This is often totally different depending on the product used.  Bits
 418           0 and 1 on port PB are usually used for I2C communication, but the
 419           kernel I2C driver sets the appropriate directions itself so you
 420           don't need to take that into consideration when setting this option.
 421           If you don't know what to use, it is always safe to put all as
 422           inputs.
