Hello Ralph, Is it possible to use an external signal to trigger one N2HET instruction at the same time? 1. After startup, the NHET code execute 1 or 2 instructions and waits for the trigger to start counter and generate PWMs 2. Both MCUs output a pulse on GIO or NHET pins. For example MCU0--GIOA[0], MCU1--GIOA[1] 3. GIOA[0] and GIOA[1] are connected to a logic gate as input, the Gate output feeds to one NHET pin (for example N2HET1[0]) of MCU0 and MCI1 4. The rising edge or falling of N2HET1[0] triggers one instruction to start the counter. For example to trigger a BR instruction
