3.3.4ABORT# Switch

The ABORT# switch is recessed to reduce the likelihood of accidental activation. The ABORT# signal is connected to the Harrier Abort Switch (ABTSW_L) input and generates an MPIC internal interrupt. This signal is debounced in the Harrier ASIC.

3.3.5RESET# Switch

The RESET# switch is recessed to reduce the likelihood of accidental activation. The signal is connected to the Harrier Reset Switch (RSTSW_L) input which will generate a Harrier Reset Out, which is ORed with the board reset logic. This signal is debounced in the Harrier ASIC.

3.3.6Front Panel LEDs

The CPCI-6020 provides these LEDs on the front panel. Refer to the Harrier Application Specific Integrated Circuit (ASIC) Programmer’s Reference guide for details of the BDFL bit.

3.4Connector Pin Assignments

The following tables describe connectors available on the CPCI-6020 base board. Note that the pin assignments for connectors J3, J4 and J5 apply to the transition module, as well as the CPCI-6020.

3.4.1CompactPCI Bus Connectors

The CPCI-6020 implements a 64-bit CompactPCI interface on connectors J1 and J2. Each of these connectors conform to the CompactPCI specification. The pinout for connectors J1 and J2 are shown in Table 3-6 on page 61 below and Table 3-7 on page 61.

zJ1 is a 110 pin AMP Z-pack 2 mm hard metric type A connector with keying for +3.3 V or +5 V

zJ2 is a 110 pin AMP Z-pack 2 mm hard metric type B connector
