Two watchpoint units
Test access port accessible through a JTAG protocol
Debug communication channel
Debug Unit
Two-pin UART
Debug communication channel interrupt handling
Chip ID Register
IEEE1149.1 JTAG Boundary-scan on all digital pins
7.3
Memory Controller
Bus Arbiter
Handles requests from the ARM7TDMI and the Peripheral DMA Controller
Address decoder provides selection signals for
Three internal 1 Mbyte memory areas
One 256 Mbyte embedded peripheral area
Abort Status Registers
Source, Type and all parameters of the access leading to an abort are saved
Facilitates debug by detection of bad pointers
Misalignment Detector
Alignment checking of all data accesses
Abort generation in case of misalignment
Remap Command
Remaps the SRAM in place of the embedded non-volatile memory
Allows handling of dynamic exception vectors
Embedded Flash Controller
Embedded Flash interface, up to three programmable wait states
Prefetch buffer, buffering and anticipating the 16-bit requests, reducing the required wait states
Key-protected program, erase and lock/unlock sequencer
Single command for erasing, programming and locking operations
Interrupt generation in case of forbidden operation
