9.4JTAG Test Access Port (TAP) Signals
| Pin Name | Type | Pin | Function | 
| 
 | 
 | 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. |
