JTAG Specification
These products support a limited set of JTAG functions as in IEEE standard 1149.1.
Disabling the Test Access Port
It is possible to use this device without utilizing the TAP. To disable the TAP controller without interfering
with normal operation of the device, TCK must be tied to V
SS
to preclude mid level inputs.
TDI and TMS are designed so an undriven input will produce a response identical to the application of a
logic 1, and may be left unconnected. But they may also be tied to V
DD
through a 1k resistor.
TDO should be left unconnected.

Description
TCK
2R
Test clock input. All inputs are captured on the rising edge of
TCK and all outputs propagate from the falling edge of TCK.
TMS
10R
Test mode select. This is the command input for the TAP
controller state machine.
TDI
11R
Test data input. This is the input side of the serial registers
placed between TDI and TDO. The register placed between
TDI and TDO is determined by the state of the TAP controller
state machine and the instruction that is currently loaded in
the TAP instruction.
TDO
1R
Test data output. Output changes in response to the falling
edge of TCK. This is the output side of the serial registers
placed between TDI and TDO.
Note: The device does not have TRST (TAP reset). The Test-Logic Reset state is entered while TMS is
held high for five rising edges of TCK. The TAP controller state is also reset on SRAM POWER-UP.
