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 1 k
resistor.
TDO should be left unconnected.
