6.8 Error signaling
The TJA1083 provides two modes for error indication:
• Simple error indication mode
• SPI mode (default mode)
SPI mode is active on power-up.
To switch to simple error indication mode, SCSN must be held LOW (connected to GND)
and SCLK held HIGH (connected to VIO) for longer than tdet(L)(SCLK) (provided a VIO
undervoltage has not occurred). When the TJA1083 is in simple error indication mode, a
rising edge on SCSN initiates a transition to SPI mode (again provided a VIO undervoltage
has not occurred); see Figure 10.
