Reset, Switch | Emerson PMPPC7448 instruction

Setup: PmPPC7448 Circuit Board

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.
