Abstract
A data processor (3) executes a debug operation by minimally intruding on the real time operation of the data processor and without halting the data processor. The data processor implements a control register (40) which stores trigger response value for determining a function executed by the data processor when a breakpoint signal is asserted. The trigger response values indicates whether a central processing unit (2) of the data processor executes a special debug exception processing routine or suspends operation when the breakpoint signal is asserted.
