9.4 Functional Modes
The TLIN1039-Q1 has three functional modes of operation: normal, sleep, and standby. The next sections will describe these modes as well as how the device moves between the different modes. Figure 9-4 graphically shows the relationship while Table 9-1 shows the state of pins
Table 9-1 Operating Modes
| MODE | EN | RXD | LIN BUS TERMINATION | TRANSMITTER | COMMENT |
|---|---|---|---|---|---|
| Sleep | Low | Floating | Weak current pull-up | Off | |
| Standby | Low | Low | 45 k? | Off | Wake-up event detected, waiting on MCU to set EN |
| Normal | High | LIN bus data | 45 k? | On | LIN transmission up to 20 kbps |
