7.3.4.7 User Single Step Mode

User Single Step mode, in which the CPU single steps through the code in Program Memory, is enabled when the debugger issues the DebugStepUser JTAG instruction. From Debug mode, the OCI executes one user instruction by pulsing DebugStep active for one clock (or until the first program fetch has completed). The core responds by fetching and executing one instruction, then returning to Debug mode. DebugAck is negated during the step.
