Memory map and register descriptions
30.1.2 Block diagram
This is a block diagram of the CRC.
30.1.3 Modes of operation
Various MCU modes affect the CRC module's functionality.
30.1.3.1 Run mode
This is the basic mode of operation.
30.1.3.2 Low power modes (wait or stop)
Any CRC calculation in progress stops when the MCU enters a low power mode that
disables the module clock. It resumes after the clock is enabled or via the system reset for
exiting the low power mode. Clock gating for this module is MCU dependent.
