SAM9260 [SUMMARY]
6221LS–ATARM–15-Oct-12
z
8-level Priority Controller
z
Drives the Normal Interrupt of the processor
z
Handles priority of the interrupt sources 1 to 31
z
Higher priority interrupts can be served during service of lower priority interrupt
z
Vectoring
z
Optimizes Interrupt Service Routine Branch and Execution
z
One 32-bit Vector Register per interrupt source
z
Interrupt Vector Register reads the corresponding current Interrupt Vector
z
Protect Mode
z
Easy debugging by preventing automatic operations when protect models are enabled
z
Fast Forcing
z
Permits redirecting any normal interrupt source on the Fast Interrupt of the processor
9.11 Debug Unit
z
Composed of two functions:
z
Two-pin UART
z
Debug Communication Channel (DCC) support
z
Two-pin UART
z
Implemented features are 100% compatible with the standard Atmel
®
USART
z
Independent receiver and transmitter with a common programmable Baud Rate Generator
z
Even, Odd, Mark or Space Parity Generation
z
Parity, Framing and Overrun Error Detection
z
Automatic Echo, Local Loopback and Remote Loopback Channel Modes
z
Support for two PDC channels with connection to receiver and transmitter
z
Debug Communication Channel Support
z
Offers visibility of and interrupt trigger from COMMRX and COMMTX signals from the ARM Processor’s ICE
