CP3004-SA
3.3.16 General Purpose Output Register (GPOUT)
The General Purpose Output Register holds the general purpose output signals of the rear I/O Compact-
PCI connector J2. This register can only be used if the CP3004-SA is ordered as a rear I/O version and
the rear I/O GPIO operation is configured through the dedicated rear transition module configuration
signal on the CompactPCI connector J2.
3.3.17 General Purpose Input Register (GPIN)
The General Purpose Input Register holds the general purpose input signals of the rear I/O CompactPCI
connector J2. This register can only be used if the CP3004-SA is ordered as a rear I/O version and the
rear I/O GPIO operation is configured through the dedicated rear transition module configuration sig-
nal on the CompactPCI connector J2.
Note:
The CP3004-SA provides pull-up resistors on the rear I/O signal pins
GPI[4..0], which leads
to the default setting “input high” if the inputs are not connected.
The general purpose inputs support 3.3V LVTTL signaling only (not 5V-tolerant).
