Product features
Doc ID 14395 Rev 5
5.3.2
Debug module
The non-intrusive debugging module features a performance close to a full-flavored
emulator. Besides memory and peripheral operation, CPU operation can also be monitored
in real-time by means of shadow registers.
●
R/W of RAM and peripheral registers in real-time
●
R/W for all resources when the application is stopped
●
Breakpoints on all program-memory instructions (software breakpoints), except the
interrupt vector table
●
Two advanced breakpoints and 23 predefined breakpoint configurations
5.4
Clock and clock controller
The clock controller distributes the system clock coming from different oscillators to the core
and the peripherals. It also manages clock gating for low-power modes and ensures clock
robustness.
5.4.1
Features
●
Clock sources:
–
Internal 16 MHz and 128 kHz RC oscillators
–
Crystal/resonator oscillator
–
External clock input
●
Reset: After reset the microcontroller restarts by default with an internal 2-MHz clock
(16 MHz/8). The clock source and speed can be changed by the application program
as soon as the code execution starts.
●
Safe clock switching: Clock sources can be changed safely on the fly in run mode
through a configuration register. The clock signal is not switched until the new clock
source is ready. The design guarantees glitch-free switching.
●
Clock management: To reduce power consumption, the clock controller can stop the
clock to the core, individual peripherals or memory.
●
Wakeup: In case the device wakes up from low-power modes, the internal RC
oscillator (16 MHz/8) is used for quick startup. After a stabilization time, the device
switches to the clock source that was selected before halt mode was entered.
●
Clock security system (CSS): The CSS permits monitoring of external clock sources
and automatic switching to the internal RC (16 MHz/8) in case of a clock failure.
●
Configurable main clock output (CCO): This feature permits to outputs a clock signal
for use by the application.
