The interface card provides four options for a clock source to the parallel EVM interface with use of a
2-mm shunt on J14.

External interrupts shown in this table are based on the TMS320C6711 DSK.
Jumper W7 on the 5–6K Interface Board revision B expands the interrupt capabilities of certain
data-converter EVMs. W7 controls the signal applied to J13 via single-gate inverter U7. When a shunt is
installed on W7-pins 1-2 (default), the interrupt signal is applied directly to J13. Installing the shunt on
W7-pins 2-3 provides an interrupt inverted signal to J13 via U7.
