Frame Error Counter: this error counter is incremented by 1 for every received frame error detected (stuff bit, CRC or CRC delimiter form error). The counter is decremented by 1 for every correctly received CAN frame assuming the counter is not zero. If the device is set for passive on CAN with flexible data rate frames, any frame detected as a CAN FD frame will have no impact on the frame error counter (no increment or decrement). If the frame counter reaches FRAME_CNT_THRESHOLD[7:0] value, the next increment overflows the counter, set FRAME_OVF flag. The counter is reset by the following: enabling the frame detection or tSILENCE detection.
