The operand (longword) data is written to the specified debug module register. All 32 bits of the register
are altered by the write. DSCLK must be inactive while the debug module register writes from the CPU
accesses are performed using the WDEBUG instruction.

The ColdFire Family provides support debugging real-time applications. For these types of embedded
systems, the processor must continue to operate during debug. The foundation of this area of debug support
is that while the processor cannot be halted to allow debugging, the system can generally tolerate small
intrusions into the real-time operation.
The debug module provides three types of breakpoints—PC with mask, operand address range, and data
with mask. These breakpoints can be configured into one- or two-level triggers with the exact trigger
response also programmable. The debug module programming model can be written from either the
external development system using the debug serial interface or from the processor’s supervisor
programming model using the WDEBUG instruction. Only CSR is readable using the external
development system.
