3.2 Resets
All resets for the C29x PCIe card are handled by CPLD. A power-on-reset is initiated by
pressing the power switch, if the board is in a chassis. A warm reset is initiated by
pressing SW1 on the board. A warm reset can also be initiated using software, by
asserting the HRESET_REQ line from the processor.
