➀ When control signals are not affected to user system circuit
When the control signals in the standard serial I/O mode are not used or not affected to the user
system circuit, they can be connected as shown in Figure 2.14.5.
Fig. 2.14.5 Connection example in standard serial I/O mode (1)
➁ When control signals are affected to user system circuit-1
Figure 2.14.6 shows an example that the jumper switch cut-off the control signals not to supply
to the user system circuit in the standard serial I/O mode.
