|
| No. |
|
|
|
|
|
TCK | Input | B8 | The test clock (TCK) signal provides timing for test |
|
|
| operations that are carried out using the IEEE |
|
|
| P1149.1 test access port. |
|
|
|
|
TMS | Input | B9 | The test mode select (TMS) signal controls the test |
|
| operations that are carried out using the IEEE | |
|
|
| P1149.1 test access port. TMS is sampled on the |
|
|
| rising edge of TCK. TMS has an integral |
|
|
| resistor. |
|
|
|
|
TDI | Input | D10 | The test data input (TDI) signal carries test data into |
|
| the | |
|
|
| port. TDI is sampled on the rising edge of TCK. TDI |
|
|
| has an integral |
|
|
|
|
TDO | Tristate | A9 | The test data output (TDO) signal carries test data |
|
|
| out of the |
|
|
| access port. TDO is updated on the falling edge of |
|
|
| TCK. TDO is a tristate output which is inactive |
|
|
| except when scanning of data is in progress. |
|
|
|
|
TRSTB | Input | C9 | The |
|
| an asynchronous | |
|
|
| reset via the IEEE P1149.1 test access port. |
|
|
| TRSTB is a Schmitt triggered input with an integral |
|
|
| |
|
|
| Note that when not being used, TRSTB must be |
|
|
| connected to the RSTB input. |
