Debug and Test Features
The Peripheral DMA Controller handles transfer requests from the channel according to the fol-
lowing priorities (Low to High priorities):
Table 7-5.
• Debug access to all memory and registers in the system, including Cortex-M3 register bank
• Serial Wire Debug Port (SW-DP) and Serial Wire JTAG Debug Port (SWJ-DP) debug access
• Flash Patch and Breakpoint (FPB) unit for implementing break points and code patches
• Data Watchpoint and Trace (DWT) unit for implementing watch points, data tracing, and
• Instrumentation Trace Macrocell (ITM) for support of printf style debugging
• IEEE
Instance name
