Section 4 User System Interface Circuit

The microcomputer (H8S/2168) is installed in this user system interface cable for emulating the
LPC function. An interface circuit, as shown in figure 11, is provided for the user system interface
signal of the H8S/2168. Figure 12 and table 2 show the settings of switches.
