Peter McGoron 9f76e03028 Minor SPI fixes and Interconnect fix 
The previous code did not properly assign all values on all cases,
and did not properly assign values (master interfaces, which are
poorly named because they are the interfaces to the master, connect
to the slave lines directly in the interconnect)
