Debug Communication Channel
breakpoints
Figure 27-2. JTAG-based Debugger
The Debug Communication Channel (DCC) consists of a pair OCD registers with associated
handshake logic, accessible to both CPU and JTAG. The registers can be used to exchange
data between the CPU and the JTAG master, both runtime as well as in debug mode.
One of the most fundamental debug features is the ability to halt the CPU, to examine registers
and the state of the system. This is accomplished by breakpoints, of which many types are
available:
When a breakpoint triggers, the CPU enters debug mode, and the D bit in the Status Register is
set. This is a privileged mode with dedicated return address and return status registers. All privi-
leged instructions are permitted. Debug mode can be entered as either OCD mode, running
instructions from JTAG, or monitor mode, running instructions from program memory.
• Unconditional breakpoints are set by writing OCD registers by JTAG, halting the CPU
• Program breakpoints halt the CPU when a specific address in the program is executed.
• Data breakpoints halt the CPU when a specific memory address is read or written, allowing
• Software breakpoints halt the CPU when the breakpoint instruction is executed.
