Reset
The reset signals are routed to the CPLD, unless stated otherwise. See Chapter 7 for the
reset registers. The following sources can reset the PmPPC7448:
Power-on: This causes a hard reset to the entire board, including the PCI interfaces.
Front panel: This reset switch is accessible through a small hole in the front panel and causes a hard reset
to the entire board, including the PCI interfaces.
Caution: Use minimal force when pressing the front panel reset switch. Excessive force may damage
the switch.
PCI RESET: This causes a hard reset to the entire board, including the PCI interfaces.
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.
PMC TRST: This is routed directly to the MV64460 TRST.
Software controlled: The software controlled resets are described in the Reset Command register, Register
Map 7-2.
