3.2.4 ITM Trace Connections
If the ITM trace is enabled, the ITM will take control over the pin PA23, irrespectively of the I/O
Controller configuration. The Serial Wire Trace signal is available on pin PA23
3.2.5 Oscillator Pinout
The oscillators are not mapped to the normal GPIO functions and their muxings are controlled
by registers in the System Control Interface (SCIF) or Backup System Control Interface (BSCIF).
Refer to the Section 15. ”System Control Interface (SCIF)” on page 308 and Section 15. ”Backup
System Control Interface (BSCIF)” on page 308 for more information about this.
