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.
