SLLA578 June 2022 TLIN1431-Q1
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 be transitioned to any of the following states through a SPI command, setting the LIN_MODE bits of the LIN_CNTRL register (8’h1D[7:6]) to any of the following values:
In addition, the device will transition to restart mode if a UVSUP, nRST, watchdog failure, or SOFT_RST event occurs. It will transition to fail-safe mode (if enabled) or sleep mode (if FSM disabled) if a UVCC, OVCC, thermal shutdown, or VCC short-circuit event occurs.
