COP HRESET:

This reset is activated by the common on-chip processor (COP) debugger interface via a
header located on the Development Mezzanine Card (DMC). It causes a hard reset to the
entire board, including the PCI interfaces.

COP SRESET:

This reset is activated by the COP debugger interface and causes a soft reset to the Frees-
cale MPC7448 and a reset to Flash.

COP TRST:

This is routed directly to the MPC7448 TRST.
