9.4.1 Operating States
Figure 9-4 Operating States DiagramTable 9-1 Operating Modes
| MODE | EN | RXD | LIN BUS TERMINATION | INH | TRANSMITTER | COMMENTS |
|---|---|---|---|---|---|---|
| Sleep | Low | Floating | Weak current pullup | High impedance | Off | |
| Standby | Low | Low | 30 k? (typical) | High | Off | Wake-up event detected, waiting on MCU to set EN |
| Normal | High | LIN bus data | 30 k? (typical) | High | On | LIN transmission up to 20 kbps |
