Debug Unit

– One 32-bit Vector Register per interrupt source

– Interrupt Vector Register reads the corresponding current Interrupt Vector

• Protect Mode

– Easy debugging by preventing automatic operations

• Fast Forcing

– Permits redirecting any normal interrupt source on the Fast Interrupt of the

processor

• General Interrupt Mask

– Provides processor synchronization on events without triggering an interrupt

• Optimizes the power consumption of the whole system

• Embeds and controls:

– One Main Oscillator and One Slow Clock Oscillator (32.768Hz)

– Two Phase Locked Loops (PLLs) and Dividers

– Clock Prescalers

• Provides:

– the Processor Clock PCK

– the Master Clock MCK

– the USB Clocks, UHPCK and UDPCK, respectively for the USB Host Port and the

USB Device Port

– Programmable automatic PLL switch-off in USB Device suspend conditions

– up to thirty peripheral clocks

– four programmable clock outputs PCK0 to PCK3

• Four operating modes:

– Normal Mode, Idle Mode, Slow Clock Mode, Standby Mode

• One Period Interval Timer, 16-bit programmable counter

• One Watchdog Timer, 16-bit programmable counter

• One Real-time Timer, 20-bit free-running counter

• Interrupt Generation on event

• Low power consumption

• Full asynchronous design

• Two hundred year calendar

• Programmable Periodic Interrupt

• Alarm and update parallel load

• Control of alarm and update Time/Calendar Data In

• System peripheral to facilitate debug of Atmel’s ARM®-based systems

• Composed of four functions

– Two-pin UART

– Debug Communication Channel (DCC) support

– Chip ID Registers

– ICE Access Prevention
