I'm using MC33905 SBC chip.I am configuring this SBC chip through SPI. I can read back the right device ID 0x23f4 through the SPI command 0x2580.   I  configure all the registers as per the manual described, still my current mode is INIT mode only, and it is not going to normal mode.The RESET pin change to low every 256ms,and the write command 0x5a00 which to refresh the watchdog may not work, This is my project,can anyone tell me the reason for error? please help me .thank you for all.
