This mode is entered from various other modes based upon which control method is implemented, the pin control Figure 8-24 or SPI control Figure 8-25. The LIN bus responder node termination circuit is turned on when standby mode is entered. Standby mode is signaled through a low level on RXD. See Standby Mode Application Note for more application information.
When EN (in Pin Control Mode) is set high for longer than tFM_CHANGE while the device is in standby mode the device returns to normal mode and the normal transmission paths from TXD to LIN bus and LIN bus to RXD are enabled.
During power up, the device automatically enters standby mode from restart mode. EN has an internal pull-down resistor ensuring EN is pulled low if the pin is left floating in the system.
In both pin and SPI modes, the watchdog is default on in standby mode. There is a long timeout initial window that is tINITWD that a WD trigger event must take place. In SPI mode, watchdog can be disabled when entering standby mode except for cases that the device has had a POR event.
The device automatically enters standby mode from restart mode when VCC ≥ UVCC and tRSTN_act time has expired. When in SPI communication mode, the TLIN1431x-Q1 can enter standby mode by writing a 00 to register 8'h1D[7:6] from normal or fast modes. The watchdog function is default on in standby mode. When using SPI to configure the device, the watchdog function can be configured.
