Comment: Added Chapter about EtherCAT DC.


Connect both boards (see Figure above). Voltage supply is done through the VCC33_Sockel by the Rl78RL78/G14.


Please connect both boards with each other, before you connect them per USB to your computer.

EtherCAT Distributed Clocks

The Platform RL78/G14 supports the feature EtherCAT Distributed Clocks (DC). The synchronization signal SYNC0 from the SoM is connected through the Arduino Adaptershield to the RL78/G14. To use the signal SYNC1 a bridge is needed to connect the pins 7 and 4 of the Arduino Adaptershield. Connected as shown in the figure below, both of the SYNC signals cause an interrupt on the RL78/G14.
