Product data sheet
1.7 Message Passing Mode
This mode allows the FGPO to read and transmit messages from main memory to
either an FGPI unit on another PNX15xx Series or a PNX1300 Series VI in message
passing mode.
One FGPO can broadcast to multiple receiving FGPI’s. No data interpretation is
done. Each message from the sender is read from a separate message location in
the memory buffer.
Message start and stop is signaled by the sender by separate fgpo_start and
fgpo_stop control signals.
