Soft Reset
Software can assert the SRESET# pin of the processor by programming the P0 bit in the
Processor Init Register of the Harrier MPIC appropriately.

Front Panel Resources
The CPCI-6020 front panel provides access to recessed Abort and Reset push-button
switches, Board Fail, CPU Bus Activity and Hot Swap Status LEDs, an RJ-45 Ethernet
connector, an RJ-45 serial port connector, two USB connectors and the PMC front panel.
4.10.7
ABORT# and RESET# Switches
Two push-button switches provide ABORT# and RESET# inputs to the CPCI-6020. Both
switches are 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. The RESET# 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. Each signal is
debounced in the Harrier ASIC.
