SY6970 LED (STAT Pin) Interface

This class provides control over the SY6970 STAT (status) pin, which is an open-drain output that indicates charging status.

Pin Behavior

The STAT pin indicates charging status through different patterns:

• High impedance (no pull-up): No charging
• Low (pulled to GND): Charging in progress
• Blinking (1Hz): Charge done
• Blinking (4Hz): Fault condition

Register

• REG03 Bit 6: STAT_DIS - Disable/enable STAT pin function
