- Some Programmable Device: MCU, CPU, CPLD, FPGA, SoC
- Working Programming or Configuration interface or means to boot the Programmable Device
- Timing Source (Clock), can be external or internal, must be be enabled
- Active Power to all required power domains of the Programmable Device
- Release of main Reset
- LED Connected to some user controllable I/O Port of the Programmable Device
- LED must be assembled with right polarity and proper current limiting resistor
- Valid I/O Voltage applied to the I/O Bank with the user LED
| Warning |
