Peripheral DMA Controller
The Atmel Peripheral DMA controller sets a
new standard for data transfer efficiency. If
the Peripheral DMA controller is not en-
abled, the maximum usable transfer rate on
the SPI module would be approximately 1
MBit/s, occupying the CPU with more than
50% load just moving data around. With the
Peripheral DMA controller this bottleneck is
removed and the AVR32 UC3 microcontroller
can achieve a transfer rate of 33 MBit/s on
SPI and USART with only a 15% load on the
CPU. The UC3 can even toggle the I/O pins
at 33 MHz.
Interrupt Controller
The 32-bit AVR UC3 CPU includes a multi-level interrupt
controller. Four priority levels are supported where higher
level interrupts are prioritized and executed before low level
interrupts. All peripherals can be assigned any interrupt level
and the interrupt vector addresses can be changed without
stopping the CPU. Interrupt latencies are very fast, typically
11 clock cycles including saving the register file to the stack.

A higher level interrupt will halt execution of a lower level interrupt routine. The lower level
interrupt routine will continue and finish after the higher level interrupt routine finishes.

A second interrupt at an interrupt level already being serviced, will pend until the first
