Resetting the TAP controller
The boundary-scan (JTAG) interface includes a state machine controller named the TAP
controller. To force the TAP controller into the correct state after power-up, you must
apply a reset pulse to the nTRST signal:
•
•
A clock on TCK is not necessary to reset the device.
The nTRST signal:
1.
2.
3.
4.
You must use nTRST to reset the boundary-scan interface at least once after power up.
After this the TAP controller state machine can be put into the TEST-LOGIC RESET
state to subsequently reset the boundary-scan interface.
When the boundary-scan interface or EmbeddedICE is to be used, nTRST must
be driven LOW and then HIGH again.
When the boundary-scan interface or EmbeddedICE is not to be used, the nTRST
input can be tied permanently LOW.
Selects system mode. This means that the boundary-scan cells do not intercept
any of the signals passing between the external system and the core.
Selects the IDCODE instruction.
When the TAP controller is put into the SHIFT-DR state and TCK is pulsed, the
contents of the ID register are clocked out of TDO.
Sets the TAP controller state machine to the TEST-LOGIC RESET state.
Sets the scan chain select register to
chain, if present.
