1-6
The MVME162FX can be operated as an embedded controller
without the VMEbus interface. For this option, the VMEchip2 and
the VMEbus buffers are not populated. Also, the bus grant daisy
chain and the interrupt acknowledge daisy chain have zero-ohm
bypass resistors installed.
To support this feature, certain logic in the VMEchip2 has been
duplicated in the MC2 chip. The following table defines the location
of the redundant logic. This logic is inhibited in the MC2 chip if the
VMEchip2 is present. The enables for these functions are controlled
by software and MC2 chip hardware initialization.
