3.4.3. TapActionReset

3.4.3. `TapActionReset`

This is the simplest of the TapAction subclasses, implementing a JTAG reset cycle. It has a sole private instance variable.

```
bool  firstTime
	    
```
This is used to track the first call of the process method.

Constructor

The constructor's key action is to set the firstTime instance variable to true.

`process`

On the first cycle through, the TAP state machine's resetDone flag is cleared.

This allows the base class checkResetDone method to be used to drive the reset.

In this case completion is when the TAP state machine records the reset is done, not when the checkResetDone function returns true. This means completion is signaled on the final reset cycle, rather than after the final reset cycle. See Section 3.4.2 for the explanation of this behavior.
