Error message #5: This is the number of operations before all PEs
had completed their router transfer using the 16-bit commands. Only
1/16 of the PEs can be connected at any one time, so it takes 16
operations to complete.

Error message #6: This is the exclusive OR comparison of the data
sent over the router with the data received at the other end. 16 bits
of data were sent using one
rosend16
command. Any bit set in this
word indicates an erroneous bit in the data received.
*
Error message #7: This is the exclusive OR comparison of the data
fetched over the router with the data received. 16 bits of data were
fetched using one
