7.1 Debug State Side Effects

The following are side effects of the debug state:

• The device debug mode is entered as soon as the SW-DP CTRLSTAT.CDBGPWRUPREQ bit (Refer to ARM Debug Interface v5 Architecture Specification) is set (and acknowledged by the system when the start-up sequence is complete). In this device debug mode:
  • Sleep modes behavior is changed to allow debugging
  • Debug clock is running
  • Internal clock requests are altered
• Peripherals behavior on CPU halt is controlled by DBGCTRL registers in the device's individual peripheral module.
