3.4 Inverted Clock Connector J12
Connector J12 is the source for an inverted clock signal OSC2. Figure 3-5 and
Table 3-5 give the pin assignments and signal descriptions for this connector.
Because the OSC2 signal is not present on the target cable, you should connect
this signal to your target system if you will use the OSC2 signal.
