In the example project SCB_SpiCommMaster there are two SPI components, the SPIM (master) in SCB mode and the SPIS (slave) in UDB mode. My question is: 

   

How did the internal pin of SPIM \SPIM:miso_m\ get connected to the external pin P0[1]?

   

Is there any help file or video clip explaining this step of configuring/routing the SPIM to SPIS?

In PSoC4 the routing is a bit limited. The non-UDB-components have got defaulted pins which you should use. The first build usually assigns them. For the UDB-components you are not limited with routing (except some special ports as P_4) but you are limited in the number of UDBs.

   

There are UDB Master and Slave and there is an SCB component which can be configured as either master or slave.
