11.5.2 X.86 Registers

X.86 transmit and common registers are used to control the operation of the X.86 encoder and decoder.

Register Name:			LI.TX86EDE
Register Description:			X.86 Encoding Decoding Enable
Register Address:			0D8h
Bit #	7	6	5		4	3	2	1	0
Name	-	-		-	-	-	-	-	X86ED
Default	0	0		0	0	0	0	0	0

Bit 0: X.86 Encoding Decoding (X86ED) If this bit is set to 1, X.86 encoding and decoding is enabled for the Transmit and Receive paths. The MAC Frame is encapsulated in the X.86 Frame for Transmit and the X.86 headers are checked for in the received data. If X.86 functionality is selected, the X.86 receiver byte boundary is provided by the RBSYNC signal and the DS33R11 provides the transmit byte synchronization TBSYNC. No HDLC encapsulation is performed.

Register Name:		LI.TRX86A
Register Description:		Transmit Receive X.86 Address
Register Address:		0D9h
Bit #	7	6	5	4	3	2	1	0
Name	X86TRA7	X86TRA6	X86TRA5	X86TRA4	X86TRA3	X86TRA2	X86TRA1	X86TRA0
Default	0	0	0	0	0	1	0	0

Bits 0 - 7: X86 Transmit Receive Address (X86TRA0-7)This is the address field for the X.86 transmitter and for the receiver. The register default value is 0x04.

Register Name:		LI.TRX8C
Register Description:		Transmit Receive X.86 Control
Register Address:		0DAh
Bit #	7	6	5	4	3	2	1	0
Name	X86TRC7	X86TRC6	X86TRC5	X86TRC4	X86TRC3	X86TRC2	X86TRC1	X86TRC0
Default	0	0	0	0	0	0	1	1

Bits 0 - 7: X86 Transmit Receive Control (X86TRC0-7)This is the control field for the X.86 transmitter and expected value for the receiver. The register is reset to 0x03

Register Name:		LI.TRX86SAPIH
Register Description:		Transmit Receive X.86 SAPIH
Register Address:		0DBh
Bit #	7	6	5	4	3	2	1	0
Name	TRSAPIH7	TRSAPIH6	TRSAPIH5	TRSAPIH4	TRSAPIH3	TRSAPIH2	TRSAPIH1	TRSAPIH0
Default	1	1	1	1	1	1	1	0

Bits 0 - 7: X86 Transmit Receive Address (TRSAPIH0-7)This is the address field for the X.86 transmitter and expected for the receiver. The register is reset to 0xfe.
