Manufacturing

Test Sequence:

// Validate LPR signal integrity and external circuit response
bool manufacturing_test_lpr_low() {
    // Force LPR signal low for testing
    configure_lpr_override(LowPowerRequestOutputOverride::FORCED_LOW);
 
    // Verify electrical level at pin
    if (!verify_pin_voltage_low(LPR_PIN)) {
        log_error("LPR pin not driven to low level");
        return false;
    }
 
    // Test external circuit response
    if (!verify_external_circuit_low_response()) {
        log_error("External circuit does not respond to low LPR signal");
        return false;
    }
 
    // Restore automatic operation
    configure_lpr_override(LowPowerRequestOutputOverride::NOT_FORCED);
 
    return true;
}

警告

Usage Precautions:

• May cause external circuits to enter unintended power states
• Could lead to system power management confusion if used incorrectly
• Should be followed by return to NOT_FORCED mode for normal operation
• Test external circuit compatibility before production use

註

External Circuit Considerations: When using FORCED_LOW, consider:

• External circuit may interpret signal as power management request
• Some PMICs may respond by changing supply voltages or states
• Timing requirements for external circuit state changes
• Potential impact on other system components connected to external circuits
