B•1•5	P5, P7, P8, P9, P10, P13, P14 - Logic Analyzer Connectors

These are 38 pin, SMT, high density, matched impedance connector made by AMP. They contain all MSC8101 signals unbuffered. The pinout of these connectors is shown in MSC8101ADS Sche- matics.

B•1•6 P6 - JTAG/OnCE Port Connector

P6 is a Motorola standard JTAG/ONCE connector for the DSP. It is a 14 pin 90o two row header connector with key. The pinout of P6 is shown in TABLE B1-6. "P6 - JTAG/ONCE Connector - In- terconnect Signals" below:

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

Pin No.	Signal Name	Attribute	Description
1	TDI	I	Transmit Data In. This is the JTAG serial data input of the ADS,
			sampled on the rising edge of TCK.
2	GND	P	Digital GND. Main GND plane.
3	TDO	O	Transmit Data Output. This the MSC8101’s JTAG serial data
			output driven by Falling edge of TCK.
4	GND	P	Digital GND. Main GND plane.
5	TCK	I	Test port Clock. This clock shifts in / out data to / from the
			MSC8101ADS JTAG logic. Data is driven on the falling edge of
			TCK and is sampled both internally and externally on it’s rising
			edge.
			TCK is pulled up internally by the MSC8101.
6	GND	P	Digital GND. Main GND plane.
7	N.C.	-	Not Connected.
8	KEY	-	No pin in connector. Serve for correct plug insertion. Not
			Connected.
