How to use the DBGMCU HAL module driver

The DBGMCU HAL driver can be used as follows:

Use these three API sets to:

1. Identify the device: Use this feature to get information about the device.

   • Get the device revision:

     • Get the device revision with HAL_DBGMCU_GetRevisionID().

   • Get the device identifier:

     • Get the device identifier with HAL_DBGMCU_GetDeviceID().

2. Debug during low power mode: Use the following APIs to debug peripherals during low power modes.

   • Enable or disable the debug module during Sleep, Stop and Standby modes:

     • Use HAL_DBGMCU_EnableDebugLowPowerMode() to enable the debug module and HAL_DBGMCU_DisableDebugLowPowerMode() to disable the debug module.

   • Check whether the debug module is enabled during Sleep, Stop and Standby modes:

     • Use HAL_DBGMCU_IsEnabledDebugLowPowerMode() to check the debug module status.

3. Freeze and unfreeze clock peripherals: The DBGMCU peripheral allows certain peripherals to be suspended in debug mode when the CPU is halted.

   • Freeze and unfreeze PPPi peripherals:

     • Use HAL_DBGMCU_PPPi_Freeze() to freeze PPPi peripherals and HAL_DBGMCU_PPPi_UnFreeze() to unfreeze them.
