The LED Control Register can only be used if the General Purpose LEDs indicated in the "LED
Configuration Register" are configured in General Purpose Mode. The status of certain LEDs
can be obtained by writing a "Get LEDX" command where "x" is the LED number (color bits
are ignored) followed by a simple read.

4.3.16. General Purpose Output Register (GPOUT)

The General Purpose Output Register holds the general purpose output 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.
