The dcsr->halt indicates whether to enter debug mode due to halt_on_reset. The variable only depends on whether the -H flag exists or not.
This commit proposes entering the debug mode only once and resetting the dcsr->halt. (Without the commit, the step() will always enter the debug mode with the -H flag.)
I need help confirming that the debugging software expects this behavior. @rtwfroody
