byte area. This keyword must be entered via the SWIM interface to temporarily unlock the
device.
If desired, the temporary unlock mechanism can be permanently disabled by the user
through OPT6/NOPT6 option bytes.
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.

User trimming
The register CLK_HSITRIMR with two trimming bits plus one additional bit for the sign
permits frequency tuning by the application program. The adjustment range covers all
possible frequency variations versus supply voltage and temperature. This trimming does
not change the initial production setting.
Clock sources

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.
