FPB (Flash Patch Breakpoint)
DWT (Data Watchpoint and Trace)
SW-DP and JTAG-DP Selection Mechanism
When the Serial Wire Debug Port is active, TDO/TRACESWO can be used for trace. The asyn-
chronous TRACE output (TRACESWO) is multiplexed with TDO. So the asynchronous trace
can only be used with SW-DP, not JTAG-DP.
Table 14-2.
SW-DP or JTAG-DP mode is selected when JTAGSEL is low. It is not possible to switch directly
between SWJ-DP and JTAG boundary scan operations. A chip reset must be performed after
JTAGSEL is changed.
Debug port selection mechanism is done by sending specific SWDIOTMS sequence. The JTAG-
DP is selected by default after reset.
The FPB:
The FPB unit contains:
The DWT contains four comparators which can be configured to generate the following:
