Albatron Technology ARM11/Cortex-A8 BDI Target B Connector Signals, Returned Jtag Test Clock

bdiGDB for GNU Debugger, BDI2000 (ARM11/Cortex-A8)			User Manual	10
BDI TARGET B Connector Signals:
Pin	Name	Describtion
1	TDO	JTAG Test Data Out
		This input to the BDI2000 connects to the target TDO line.
2	reserved
3	TDI	JTAG Test Data In
		This output of the BDI2000 connects to the target TDI line.
4	reserved
5	RTCK	Returned JTAG Test Clock
		This input to the BDI2000 connects to the target RTCK line.
6	Vcc Target	1.8 – 5.0V:
		This is the target reference voltage. It indicates that the target has power and it is also used
		to create the logic-level reference for the input comparators. It also controls the output logic
		levels to the target. It is normally fed from Vdd I/O on the target board.
		3.0 – 5.0V with Rev. A/B :
		This input to the BDI2000 is used to detect if the target is powered up. If there is a current
		limiting resistor between this pin and the target Vdd, it should be 100 Ohm or less.
7	TCK	JTAG Test Clock
		This output of the BDI2000 connects to the target TCK line.
8		JTAG Test Reset
	TRST
		This open-drain / push-pull output of the BDI2000 resets the JTAG TAP controller on the
		target. Default driver type is open-drain.
9	TMS	JTAG Test Mode Select
		This output of the BDI2000 connects to the target TMS line.
10	reserved
11	reserved
12	GROUND	System Ground
13		System Reset
	RESET
		This open-drain output of the BDI2000 is used to reset the target system.
