Normal mode is the regular operating state of the TLIN1431-Q1, in which TXD is passed to LIN and LIN is passed to RXD at the LIN-specified maximum of 20 kbps.

From normal mode, the device can transition to sleep more or standby mode. To transition to low-power sleep mode, implement the following configuration for at least t_EN:

• EN = low
• TXD = low
• nRST = high

To transition to standby mode, implement the following configuration for at least t_{FM_CHANGE}:

• EN = low
• TXD = high
• nRST = high

In addition, the device will transition to restart mode if a UV_SUP, nRST, or watchdog failure event occurs. It will transition to fail-safe mode if a UV_CC, OV_CC, thermal shutdown, or V_CC short-circuit event occurs.
