Remark The sections enclosed in broken lines indicate parts that are attached to the parts board.
<2> Prepare the IE-784937-NS-EM1.
<3> Remove the parts board that is mounted in the IE-784937-NS-EM1’s socket (the socket marked as USCLK).
<4> Connect the parts board (from <1> above) to the socket (USCLK) from which the parts board was removed
(see <3> above). Check the pin 1 mark to make sure the board is mounted in the correct direction.
<5> Connect the IE-784937-NS-EM1 to the IE-78K4-NS.
The above steps configure the circuit and enable supply of the clock from the mounted resonator to the emulation
device.
