– External clock input
– Internal, user-trimmable 16 MHz RC
– Internal low-power 128 kHz RC
 Clock security system with clock monitor
 Power management:
– Low-power modes (wait, active-halt, halt)
– Switch-off peripheral clocks individually
 Permanently active, low-consumption power-
on and power-down reset
Interrupt management
