36.11 Microcontroller debug unit (DBGMCU)
DBGMCU is a component containing a number of registers that control the power and clock
behavior in debug mode. It allows the debugger (or the debug software) to perform the
following tasks:
•
Maintain the clock and power to the processor cores when in low-power modes (Sleep,
Stop or Standby).
•
Maintain the clock and power to the system debug and trace components when in
low-power modes.
• Stop the clock to certain peripherals (such as watchdogs, timers, RTC) when the
processor core is stopped in debug mode.
DBGMCU registers are not reset by a system reset, only by a power on reset. They are
accessible to the debugger via the CPU AHB access port at base address 0xE0042000.
Note: DBGMCU is not a standard CoreSight component, consequently it does not appear in the
ROM table.
