/**
 * TI MSP-TS430D8 8-pin target socket board reference circuit.
 *
 * J5 power selection:
 *   - short pins 2-3 for power from the MSP debug tool
 *   - short pins 1-2 for an externally powered target / VCC sensing
 *
 * J6 is normally shorted and can be opened to measure target supply current.
 * J4 is normally shorted and can be opened to disconnect the P1.2 LED.
