(b) Bit strobe
As shown in the following diagram, the communication method by which
the communication with each slave node is repeated, as described from 1)
to 4), is the bit strobe communication. The connection that uses this
communication is the bit strobe connection.
1) Output information of a maximum of one bit is transmitted
simultaneously to each slave node.
2) The slave node transmits the input data by setting the transmission of
1) to trigger.
3) The slave node transmits the input data by setting the transmission of
1) to trigger.
4) The slave node transmits the input data by setting the transmission of
1) to trigger.
