CP3004-SA
3.3.4 Control Register 1 (CTRL1)
The Control Register 1 holds board-specific control information.
Note:
The reset value of the SCOMA bit depends on the board version ordered. If the CP3004-SA
is ordered as a rear I/O version, the reset value is 0. If the CP3004-SA is ordered as a front
I/O version, an automatic switch over to the 8 HP extension module is processed per de-
fault.
