Functions | |
| void | TapStateInit (void) |
| TAP controller initialization. | |
| void | TmsHighTransition (void) |
| State transition with TMS set to high. | |
| void | TmsLowTransition (void) |
| State transition with TMS set to low. | |
| int | TapStateChange (u_char state) |
| Change TAP state. | |
| void | TapStateInc (void) |
| Increment the TAP state. | |
Variables | |
| u_char | tapState |
| Current state of the TAP controller. | |
The order of the defined TAP state codes is critical and should reflect the TAP state transistions.

Change TAP state. Moves the TAP (Test Access Port) controller of the target to the specified state. Trying to enter Exit2-DR or Exit2-IR from any other state except Pause-DR or Pause-IR resp. will result in an error.
