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. In case 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 will overflow the counter, set FRAME_OVF flag. The counter is reset by the following: enabling the frame detection or tSILENCE detection.
