3.2.1 VME Boot

The VM162/VM172 normally boots from the FLASH memory on the DM60x piggyback. In some ap-
plications it may be useful to boot either from the VMEbus or the optionally assembled EPROM.

3.2.4 VME SYSRES*

As long as the 5V supply is not within the VMEbus specification, the VM162/VM172 uses the VMEbus
RESET line. This behaviour may not be wanted in multi-master configurations and can be disconnected.
