Error Capture Register, Errorcode, TX Mode | Lantronix DSTni-EX

Error Capture Register

The Error Capture register captures the most recent error event with the frame reference pointer, rx- and tx-mode and the associated error code.

	Bits	Field Name	Description
	15:13	Err[2:0]	Error_code
			000 = no error (default)
			001 = crc_err
			010 = form_err
			011 = ack_err
			100 = stuff_err
			101 = bit_err
	12:8	FR[4:0]	frame_ref_Field
			This is the frame reference a incoming or outgoing CAN message.
			Values are:
			00000	= stopped
			00001	= synchronize
			00101	= interframe
			00110	= bus_idle
			00111	= start_of_frame
			01000	= arbitration
			01001	= control
			01010= data
			01011	= crc
			01100	= ack
			01101	= end_of_frame
			10000	= error_flag
			10001	= error_echo
			10010	= error_del:
			11000	= overload_flag
			11001	= overload_echo
			11010	= overload_del
			Other codes are not used.
	7	TX_MOD	TX Mode
			1 = transmitting data.
			0 = not in TX mode (receiving or idle).
	6	RX_MOD	RX Mode
			1 = receiving data.
			0 = not in RX mode (transmitting or idle).
	5:0	FRB[5:0]	frame_ref_bit_nr
			A 6-bit vector that counts the bit numbers in one field.
			Example: if field = “data” = “01010”, “bit_nr” = “000000”, and
			“tx_mode” = ‘1’, it indicates that the first data bit is being
			transmitted.
