20.6 Debug notes

User manual
Table 321. Serial Wire Debug pin description
Important: The user should be aware of certain limitations during debugging. The most
important is that, due to limitations of the ARM Cortex-M3 integration, the LPC13xx cannot
wake up in the usual manner from Deep-sleep mode. It is recommended not to use this
mode during debug.
Another issue is that debug mode changes the way in which reduced power modes work
internal to the ARM Cortex-M3 CPU, and this ripples through the entire system. These
differences mean that power measurements should not be made while debugging, the
results will be higher than during normal operation in an application.
During a debugging session, the System Tick Timer is automatically stopped whenever
the CPU is stopped. Other peripherals are not affected.
Remark: Note that the debug mode is not supported in any of the reduced power modes.

Description
Serial Wire Clock. This pin is the clock for debug logic when in the
Serial Wire Debug mode (SWDCLK).
Serial wire debug data input/output. The SWDIO pin is used by an
external debug tool to communicate with and control the LPC13xx.
Serial Wire Output. The SWO pin optionally provides data from the
ITM and/or the ETM for an external debug tool to evaluate.
