21.1.2
The principal features of the debug modes and the watchpoint monitor are as follows:
21.1.3
The LBC, and DDR SDRAM interfaces all have debug modes, which are controlled by values on
configuration inputs during the power-on reset (POR) sequence, as shown in
controller can also drive debug information on either MSRCID[0:4] or MECC[0:5]. See
“Source and Target ID,”
signals in these modes.
Note that both the watchpoint monitor and trace buffer also operate in a variety of modes.

Signal
LBC and DDR interface source ID and data-valid indicators
— LBC or DDR SDRAM source ID can be selected to be driven onto MSRCID[0:4]
— Source ID and data-valid indicators can be selected to be driven onto the error correcting code
Watchpoint monitor that supports
— Two-level triggering
— Programmable external trigger (TRIG_OUT)
— Interlocked with performance monitor to use its large number of counters
Trace buffer features that support
— Two-level triggering
— Programmable external trigger (TRIG_OUT)
— Interlocked with performance monitor to use its large number of counters
— 256-entry trace buffer, 64 bits each
— Programmable trace start and stop
— Can function as a second watchpoint monitor
Context ID registers that can be programmed to trigger events
(ECC) pins of the DDR interface

Local bus SDRAM information appears on MSRCID[0:4] and MDVAL.
Default value (internal pull-up resistor). DDR SDRAM information appears on
MSRCID[0:4] and MDVAL.
MECC[0:4] operate in debug mode and provide memory debug source ID and
MECC5 provides data-valid information.
Default value (internal pull-up resistor). MECC[0:4] operate in normal mode and
provide DDR SDRAM error correcting code information.
