METHOD AND APPARATUS FOR PROVIDING SECURITY FOR DEBUG CIRCUITRY
摘要
The invention relates to debug circuitry (20) and more particularly to a method and apparatus for providing security for debug circuitry (20). In one embodiment, a plurality of non-volatile elements (38) are used in providing selective disabling and re-enabling of at least a portion of the debug circuitry (20). Authentication may also be used. The present invention may use any debug interface, including standard debug interfaces such as the JTAG debug interface defined by the IEEE.
