SAM7X512/256/128 Summary
– 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
Fast Forcing
– Permits redirecting any interrupt source on the fast interrupt
General Interrupt Mask
– Provides processor synchronization on events without triggering an interrupt
9.5
Debug Unit
Comprises:
– One two-pin UART
– One Interface for the Debug Communication Channel (DCC) support
– One set of Chip ID Registers
– One Interface providing ICE Access Prevention
Two-pin UART
– USART-compatible User Interface
– Programmable Baud Rate Generator
– Parity, Framing and Overrun Error
– Automatic Echo, Local Loopback and Remote Loopback Channel Modes
Debug Communication Channel Support
