	Table 5-45. Configuration Register Definitions
Bits	Field Name		Description
15	OVR_MSG		Overwrite Last Message
			1= when FIFO is full and a new message arrives it overwrites the
			message in RxMsg3 buffer.
		0		= under the same conditions, a new message is discarded and
			no rx_msg flag is set (default).
14:12	TS[2_2:2_0]		Cfg_tseg2
			Length -1 of the second time segment. Cfg_tseg2=0 is not allowed;
			cfg_tseg2=1 is only allowed in direct sampling mode. See Figure
			5-4.
11:8	TS[1_3:1_0]		Cfg_tseg1
			Length - 1 of the first time segment (bit timing). It includes the
			propagation time segment. Cfg_tseg1=0 and cfg_tseg1=1 are not
			allowed. See Figure 5-4..
7:5	///		Reserved
4	AUTO_RES		Auto Restart
		1		= after bus off, the CAN is restarting automatically after 128
			groups of 11 recessive bits.
		0		= after bus off, the CAN must be started manually (default).
3:2	CFG_SJW1		Cfg_sjw
			Synchronization jump width - 1. sjwtseg1 ≤ and sjwtseg2 ≤
1	SAMP_MOD		Sampling Mode
		1		= three sampling points with majority decision are used.
		0		= one sampling point is used in the receiver path.
0	EDGE_MOD		Edge Mode
			1	= both edges are used.
			0	= edge from ‘ R’ to ‘ D’ is used for synchronization (default).
