AT91SAM9G20 Summary
– Source 0 is reserved for the Fast Interrupt Input (FIQ)
– Source 1 is reserved for system peripherals
– Programmable Edge-triggered or Level-sensitive Internal Sources
– Programmable Positive/Negative Edge-triggered or High/Low Level-sensitive
Three External Sources plus the Fast Interrupt signal
8-level Priority Controller
– Drives the Normal Interrupt of the processor
– Handles priority of the interrupt sources 1 to 31
– Higher priority interrupts can be served during service of lower priority interrupt
Vectoring
– Optimizes Interrupt Service Routine Branch and Execution
– 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 when protect models are
enabled
Fast Forcing
– Permits redirecting any normal interrupt source on the Fast Interrupt of the
processor
9.11
Debug Unit
Composed of two functions:
–Two-pin UART
– Debug Communication Channel (DCC) support
Two-pin UART
– Implemented features are 100% compatible with the standard Atmel
USART
– Independent receiver and transmitter with a common programmable Baud Rate
Generator
– Even, Odd, Mark or Space Parity Generation
– Parity, Framing and Overrun Error Detection
– Automatic Echo, Local Loopback and Remote Loopback Channel Modes
– Support for two PDC channels with connection to receiver and transmitter
Debug Communication Channel Support
– Offers visibility of and interrupt trigger from COMMRX and COMMTX signals from
the ARM Processor’s ICE Interface
