Flasher ARM (UM08007)
TDI
The electronic signal input to a TAP controller from the data source (upstream). Usu-
ally, this is seen connecting the J-Link / J-Trace Interface Unit to the first TAP control-
ler.
TDO
The electronic signal output from a TAP controller to the data sink (downstream).
Usually, this is seen connecting the last TAP controller to the J-Link / J-Trace Inter-
face Unit.
Test Access Port (TAP)
The port used to access a device's TAP Controller. Comprises TCK, TMS, TDI, TDO,
and nTRST (optional).
Transistor-transistor logic (TTL)
A type of logic design in which two bipolar transistors drive the logic output to one or
zero. LSI and VLSI logic often used TTL with HIGH logic level approaching +5V and
LOW approaching 0V.
Word
A 32-bit unit of information. Contents are taken as being an unsigned integer unless
otherwise stated.
