TABLE B1-6. P6 - JTAG/ONCE Connector - Interconnect Signals

Pin No.	Signal Name	Attribute	Description
9	RST	I/O,P.U.	In fact, HRESETb. When asserted by an external H/W, generates
			Hard-Reset sequence for the MSC8101. During that sequence,
			asserted by the MSC8101 for 512 system clocks. Pulled Up on
			the ADS using a 1KΩ resistor.
			When driven by an external tool, MUST be driven with an Open
			Drain gate. Failure to do so might result in permanent
			damage to the MSC8101 and / or to ADS logic.
10	TMS	I	Test Mode Select. This signal qualified with TCK in a same
			manner as TDI, changes the state of the JTAG machines. This
			line is pulled up internally by the MSC8101.
11	VDD	P	Connect to 3.3V power supply bus. May be used for Command
			Convertor power.
12	N.C.	-	Not Connected.
13
14	TRSTb	I	Test port Reset. When this signal is active (Low), it resets the
			JTAG logic of both the MSC8101. This line is pull-down on the
			ADS with a 2.2KΩ resistor, to provide constant reset of the JTAG
			logic.
B•1•7	P12 - Ethernet Port Connector

The Ethernet connector on the MSC8101ADS - P12, is a Twisted-Pair (10-Base-T) compatible connector. It is implemented with a 90o, 8-pin, RJ45 connector, signals of which are described in TABLE B1-8. "P17,P18 - T1/E1 Line Connectors Interconnect Signals" below

TABLE B1-7. P12 - Ethernet Port Interconnect Signals

	Pin	Signal Name	Description
	No.
1		TPTX(GRAY)	Twisted-Pair Transmit Data positive output from the MSC8101ADS.
2		TPTX~(BROWN)	Twisted-Pair Transmit Data negative output from the MSC8101ADS.
3		TPRX(YELLOW)	Twisted-Pair Receive Data positive input to the MSC8101ADS.
4		(RED,GREEN)	Bob Smith terminated on the MSC8101ADS.
5
6		TPRX~(BLACK)	Twisted-Pair Receive Data negative input to the MSC8101ADS.
7		(BLUE,ORANGE)	Bob Smith terminated on the MSC8101ADS.
