I am facing an issue while using UJA113x System Basis Chip (SBC).
I have programmed the NVM (0x71 to 0x74) to get out of Forced Normal Mode. by setting FNMC = 0 and SDMC = 1.
On-Startup I send the following SPI commands to device:
CMD 1: (0x0207) - Write operation at MC(Mode Control) 0x01h register, to send the device into normal mode.
CMD 2: (0x4002) - Write operation at CAN Control register 0x20h, to disable CAN transceiver shutdown(CSC bits) and select operating mode(CMC bits) to Active Mode(under voltage disabled).
I have made sure that data is available on TXDC pin . But still, I m not able to see data on CANBUS i.e. CANH and CANL (pin 21 and pin 22). I tried to see data on CANBUS through logic analyser but both both lines are at LOW level.
Are there any more registers which need to be configured ?
