• Provides:
• Five flexible operating modes:
– the Processor Clock PCK
– the Master Clock MCK, in particular to the Matrix and the memory interfaces
– the USB Device Clock UDPCK
– independent peripheral clocks, typically at the frequency of MCK
– 2 programmable clock outputs: PCK0, PCK1
– Normal Mode, processor and peripherals running at a programmable frequency
– Idle Mode, processor stopped waiting for an interrupt
– Slow Clock Mode, processor and peripherals running at low frequency
– Standby Mode, mix of Idle and Backup Mode, peripheral running at low frequency,
– Backup Mode, Main Power Supplies off, VDDBU powered by a battery
processor stopped waiting for an interrupt
