• Programmable Bus Arbiter
• Address decoder provides selection signals for
• Abort Status Registers
• Misalignment Detector
• Remap Command
– Runs at up to 55 MHz, providing 0.9 MIPS/MHz
– ARM
– Thumb
– Instruction Fetch (F)
– Instruction Decode (D)
– Execute (E)
– Two watchpoint units
– Test access port accessible through a JTAG protocol
– Debug communication channel
– Two-pin UART
– Debug communication channel interrupt handling
– Chip ID Register
– Handles requests from the ARM7TDMI, the Ethernet MAC and the Peripheral DMA
– Three internal 1 Mbyte memory areas
– One 256 Mbyte embedded peripheral area
– Source, Type and all parameters of the access leading to an abort are saved
– Facilitates debug by detection of bad pointers
– Alignment checking of all data accesses
– Abort generation in case of misalignment
– Remaps the SRAM in place of the embedded non-volatile memory
– Allows handling of dynamic exception vectors
