... Available in a 176-lead TQFP Package Description The AT91M63200 is a member of the Atmel AT91 16/32-bit Microcontroller family, which is based on the ARM7TDMI processor core. This processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. In addition, a large number of internally banked registers result in very fast exception handling, making the device ideal for real-time control applications ...

... Hence, at the end of a higher priority interrupt, the AIC returns to the previous state corresponding to the pre- ceding lower priority interrupt which had been interrupted. AT91M63200 Interrupt Handling The interrupt handler must read the AIC_IVR as soon as possible. This de-asserts the NIRQ request to the proces- sor and clears the interrupt in case it is programmed to be edge triggered ...

... In either case, an End-of-Interrupt command would be nec- essary to acknowledge and to restore the context of the AIC. This operation is generally not performed by the debug system. Hence, the debug system would become AT91M63200 42 strongly intrusive, and could cause the application to enter an undesired state. This is avoided by using Protect Mode. ...
