Understanding the enable logic prevents common bus contention issues.
| DE | RE | D | A – B Output | Receiver (R Pin) |
|----|-----|-----|----------------|------------------|

| 1 | 0 | 0 | Logic 0 (A < B)| Idle (disabled) |
| 0 | 1 | X | High-Z (tri-state) | Differential A-B > -200mV → R = 1
A-B < -200mV → R = 0
Open/shorted bus → R = 1 (fail-safe) |
Important: For half-duplex 2-wire networks (RS-485), tie RE and DE together. Connect to MCU pin for TX/RX switching.

3.2. Communication Protocol
The IC utilizes a proprietary Single-Wire Return-to-Zero (RZ) communication protocol.
- Data Structure: The data protocol consists of 24 bits per IC (8 bits for Red, 8 bits for Green, 8 bits for Blue).
- Cascade: Data is transmitted serially. The first IC in the chain intercepts the first 24 bits, processes them, and passes the remaining data to the next IC via the
DOUTpin. - Signal Reshaping: The IC reshapes the transmission signal before sending it out through
DOUT, preventing signal degradation over long cascades.
