4.14 Reset Control Logic
There are multiple sources of reset on the MVME7100ET. The following sources generate a
board level reset:
 Power-up
 Reset switch
 Watchdog timer
 System control register (BRD_RST)
 VMEbus reset
A board level hard reset generates a reset for the entire SBC including the processor, local
PCI/PCI-X buses, Ethernet PHYs, serial ports, flash devices, and PLD(s). If the MVME7100ET is
configured as the VME system controller, the VMEbus and local Tsi148 reset input are also
reset.
4.15 Real Time Clock Battery
There is an on-board battery holder that provides easy replacement of a +3.0 V button cell
lithium battery which provides back-up power to the on-board Real Time Clock. A battery
switching circuit provides automatic switching between the +3.3 V and battery voltages.
