Single-Step Mode
To execute one instruction in the debug mode, the OCI
asserts a signal debugstep for one system clock. The CPU
responds by negating debugack, executing one user or

debugger instruction, and then asserting debugack. The
OCI can set debugprog high for execution of a debugger
instruction or set debugprog low for execution of a user
instruction (see Figure 24 ).

When the CPU executes the opcode 0xA5, the core enters
debug mode and asserts the debugack signal. The

debugger responds by setting debugreq high. The CPU
leaves the debug mode when debugreq is high for at
least one clock period and then goes low.
