Emulator controlled System Reset
This signal provides the scan controller with the ability to
assert the system warm reset. When a 1 is written, this
behaves as if the external chip warm reset signal had
0
been momentarily asserted. This signal does not reset
any emulation logic. This is a self-clearing bit. This is
cleared by the assertion of the reset requested.
Writing a 0 has no effect.

0 See Table 5-17
0 When a 1 is written to this bit, the currently selected
TAPLinkMode is activated. ICEPick links the TAPs
according to these settings when the ICEPick TAP is
advanced to Run‑Test-Idle with any opcode in the IR.
