Motorola MVME3100 manual Reset Control Logic, Debug Support

Chapter 4 Functional Description

Reset Control Logic

The sources of reset on the MVME3100 are the following:

■Power-up

■Reset switch

■Watchdog timer

■System Control register bit

■VMEbus reset

A board-level hard reset generates a reset for the entire board including the MPC8540, local PCI/PCI-X buses, Ethernet PHYs, serial ports, Flash devices, and PLD(s). If the MVME3100 is configured as the VME system controller, the VME bus and local TSi148 reset input are also reset.

Debug Support

The MVME3100 provides a boundary scan header for boundary scan test access and device programming. This board also provides a separate standard COP header for MPC8540 COP emulation.
