Table 21: Pin Definition of Motor Drive Interface
The motor is driven by an exclusive circuit, and the reference circuit design is shown below.
Figure 20: Reference Circuit for Motor Connection
When the motor stops, the redundant electricity can be discharged from the circuit loop formed by diodes,
thus avoiding damage to components.
3.18. LCM Interface
SC20 series provides one LCM interface, which is MIPI_DSI standard compliant. The interface supports
high-speed differential data transmission with one 4-lane MIPI_DSI and a transmission rate of up to
1.5 Gbps/lane. It supports up to 720P resolution display.
