J14 is a three-pin by ten header that is used to establish input levels for the pin controlled two-level inputs using
jumper plugs. It also provides a means of externally driving the two-level input signals:
J8 is a 20 pin ribbon header that provides an external path to monitor the status pins.
J22 is a 10 pin ribbon header that provides an external path to serially communicate with the Any-Frequency
Precision Clock.
To control the Any-Frequency part that is on the Evaluation Board from an external serial port, open the Register
Programmer, connect to the Evaluation Board, go to Options in the top toolbar and select "Switch To External
Control Mode".
To control an Any-Frequency part that is on an external target board from the Evaluation Board using its serial port,
tie pin 9 of J22 low so that the on-board Any-Frequency part is constantly being held in reset. This will force it to
disable its SDA_SDO output buffer.
