4.3.17. 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 CP3005-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.

The CP3005-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).
