7.2. TWRPI Connectors (P26, P27)
The EVB includes two fine pitch TWRPI headers that can be used to interface to an SAI audio board
(available separately, please consult your Freescale representative) along with the 0.1” headers
mentioned in the section above. There is no EVB configuration required when using these connectors
other than to ensure the EVB is switched off prior to fitting or removing the daughtercard. The pinout of
the connectors is shown below for reference.

7.3. MLB Daughtercard Connector (P16)
There is a 40-pin interface connector on the EVB for connecting an MLB (Media Local Bus)
daughtercard. There is no hardware configuration possible at EVB level for this connector.
MLB Daughtercards are available direct from SMSC
As with all daughtercards, the EVB must be powered OFF to prevent damage to the EVB or daughter
card components.
