Figure 1-9 Example of Bit Strobe Instruction/Response
(2) Bit Strobe Response
As a slave device receives a bit strobe instruction, it transmits response data of 0 to 8
bytes to the master device. Response data varies depending on the specifications of
the slave device.
The way the S controller reads bit strobe response data from the DN611 is described
in the text dealing with communication with slave devices in Chapter 5.
