3.2.3 I/O Bit-Strobe Command/Response Messages
The Bit-Strobe Command Message is an I/O message that is transmitted
by the Master. A Bit-Strobe Command has multicast capabilities. Multiple
Slaves can receive and react to the same Bit Strobe Command. The Bit-Strobe
response is an I/O message that a Slave transmits back to the Master when
the Bit-Strobe Command has been received. Within a Slave the two messages
are received/ transmitted by a single Connection Object. The architecture is as
figure 3-5.
