DESCRIPTION
JTAG test clock input
JTAG test data input
JTAG test data output
JTAG test mode select
JTAG test logic reset (active low)
JTAG test clock output
JTAG emulation 0 I/O
EMU[1:0] = 00 - Force Debug Scan chain (ARM and ARM ETB TAPs connected)
EMU[1:0] = 11 - Normal Scan chain (ICEpick only)
JTAG emulation 1 I/O
EMU[1:0] = 00 - Force Debug Scan chain (ARM and ARM ETB TAPs connected)
EMU[1:0] = 11 - Normal Scan chain (ICEpick only)
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.
(2) Specifies the operating I/O supply voltage for each signal. See Section 5.3, Power Supplies for more detail.
(3) PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 kΩ resistor should be used.)
