... The TJA1082 has two supply pins: V The ramp up of the different power supplies can vary, depending on the state or value of a number of signals and parameters. The power-up behavior of the TJA1082 is not affected by the sequence in which power is supplied to these pins or by the voltage ramp up. ...

... Wake-up! Fig 9. Wake-up state machine 6.3.2 Bus wake-up via dedicated FlexRay data frame The TJA1082 wake flag is set when a dedicated data frame emulating a valid wake-up pattern, as shown in The Data_0 and Data_1 phases of the emulated wake-up symbol are interrupted by the Byte Start Sequence (BSS) preceding each byte in the data frame. With a data rate of 10 Mbit/s, the interruption has a maximum duration of 130 ns and does not prevent the transceiver from recognizing the wake-up pattern in the payload ...

... SCLK while pin SCSN = LOW. 6.7 TJA1082 status register The TJA1082 contains a 16-bit status register, of which bits reflect the state of the status flags, bits S5 to S10 reflect the state of the error flags and bit S15 is a parity bit. ...
Page 15
... To switch to simple error indication mode, SCSN has to be held LOW (connected to GND) and SCLK held HIGH (connected to V undervoltage has not occurred). When the TJA1082 is in simple error indication mode, a rising edge on SCSN initiates a transition to SPI mode (provided a V TJA1082_2 Product data sheet ...

... Error flags are not latched not possible to read-out the status bits in this mode. 6.9 SPI interface The TJA1082 includes a 16-bit SPI interface to enable a host to read the status register when the transceiver is in SPI mode (see While pin SCSN is HIGH, the SDO output high-impedance state. To begin a status register readout, the host must force pin SCSN LOW ...
