CompactPCI J1 Pin Assignment
Note 1 : These signals are not connected.
Note 2 : These signals are pulled high on the board.
Note 3 : These signals are pulled low on the board.
Note 4 : To support PICMG 2.1 hotswap for peripheral boards, the
backplane should bus the ENUM# signal of all peripheral
slots to the system board. The ENUM# signal is continuously
polled by the system board’s hotswap firmware and will gen-
