Clock control (CLK)

The clock controller is designed to be powerful, very robust, and at the same time easy to

use. Its purpose is to allow you to obtain the best performance in your application while at

the same time get the full benefit of all the microcontroller’s power saving capabilities.

You can manage all the different clock sources independently and distribute them to the

CPU and to the various peripherals. Prescalers are available for the master and CPU

clocks.

A safe and glitch-free switch mechanism allows you to switch the master clock on the fly

from one clock source to another one.

EMC-hardened clock configuration registers

To protect the application against spurious write access or system hang-up, possibly caused

by electromagnetic disturbance, the most critical CLK registers are implemented as two

bitfields that must contain complementary values. Mismatches are automatically detected

by the CLK, triggering an EMC reset and allowing the application to cleanly recover normal

operations. See CLK register description for more details.
