Staged Pins

Staged Pins

The PICMG CompactPCI hot swap specification provides for three separate pin lengths in order to control the insertion and extraction voltages and to notify the system when boards are inserted or extracted.

The longest pins, which include VCC pins and GND pins, are the first to mate during the insertion process and the last to break contact during extraction. These pins are used to supply power to pre-charge the PCI interface signals to a neutral state before they contact the bus. This pre- charging serves to minimize the capacitive effects of the board as it makes or breaks contact with the bus.

The medium-length pins carry PCI and other signal traffic.

The shortest pins are used to assert signals, including BD_SEL#. During insertion, the BD_SEL# signal enables the board to attach to the local PCI bus. On extraction, it causes the board to logically and electrically disconnect from the PCI bus before the bus pins physically break contact with the bus.

BD_SEL#

BD_SEL# is asserted by one of the pins that mate last on insertion and break first on extraction. On insertion, the signal tells the board to connect to the PCI bus. On extraction this pin breaks first, causing the board to logically and electrically disconnect from the PCI bus before the PCI bus pins physically break contact with the bus.

ENUM#

An ENUM interrupt is generated when a board is hot inserted into the CPX8216 chassis, or when an operator trips the board microswitch by raising its ejector handles. The signal informs the active CPU that the status of a board has changed. The CPU then identifies the board by polling the INSert and EXTract bits in all of the boards’ Control Status Registers.
