Test Serial Data Out (5V Tolerant Three-state Output):
JTAG serial data is output on this pin on the falling edge of
TCK. This pin is held in high impedance state when JTAG
is not enabled.
Test Reset (5V Tolerant Input with internal pull-up):
Asynchronously initializes the JTAG TAP controller by
putting it in the Test-Logic-Reset state. This pin should be
pulsed low during power-up to ensure that the device is in
the normal functional mode.
Device Reset (5V Tolerant Input with internal pull-up):
This input (active LOW) puts the device in its reset state
that disables the LSTo0 - 63 driver and drives the BSTo0 -
63, LCSTo-3 outputs to high. It also clears the device
registers and internal counters. To ensure proper reset
action, the reset pin must be held low for longer than
500ns. A delay of 100µs must also be applied before the
first microprocessor access is performed after the RESET
pin is set high, this delay is required for the initialization of
the APLL.
In normal operation, this input MUST be connected to
ground.

Local Serial Input Streams 0 to 63 (5V Tolerant
Inputs): These inputs accept data rates of 8.192 Mb/s
with 128 channels per stream.
