13.2.4. Programming the debug unit

The ARM1136JF-S debug unit is programmed using CoProcessor 14 (CP14). CP14 provides:

  • instruction address comparators for triggering breakpoints

  • data address comparators for triggering watchpoints

  • a bidirectional Debug Communication Channel (DCC)

  • all other state information associated with ARM1136JF-S debug.

CP14 is accessed using coprocessor instructions in Monitor debug-mode, and certain debug scan chains in Halting debug-mode, see Chapter 14 Debug Test Access Port to learn how to access the ARM1136JF-S debug unit using scan chains.
