CRST
CPCI reset input when the CP3005 is in a peripheral slot:
0 = Disable CPCI reset to board
1 = Enable CPCI reset to board

SCOMA
COMA routing selection:
0 = Rear I/O
1 = Extension module
The reset value of the SCOMA bit depends on the board version ordered. If the CP3005 is
ordered as a rear I/O version, the reset value is 0. If the CP3005 is ordered as a front I/O
version, an automatic switch over to the 8HP extension module is processed per default.
