ARM920T

Features:

The ARM9TDMI processor core also incorporates a sophisticated debug unit to allow both software tasks and external debug hardware to perform hardware and software breakpoint,single stepping, register, and memory access. This functionality is made available to software as a coprocessor and is accessible from hardware via the JTAG port. Full-speed, real-time execution of the processor is maintained until a breakpoint is hit. At this point control is passed either to a software handler or to JTAG control
