Debug and Test Features
Integrated Embedded In-circuit Emulator Real-Time
– Two real-time Watchpoint Units
– Two Independent Registers: Debug Control Register and Debug Status Register
– Test Access Port Accessible through JTAG Protocol
– Debug Communications 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
Bus Matrix
Five Masters and Five Slaves handled
– Handles Requests from the ARM926EJ-S, USB Host Port, LCD Controller and the
Peripheral DMA Controller to internal ROM, internal SRAM, EBI, APB, LCD
Controller and USB Host Port.
– Round-Robin Arbitration (three modes supported: no default master, last accessed
default master, fixed default master)
– Burst Breaking with Slot Cycle Limit
One Address Decoder Provided per Master
– Three different slaves may be assigned to each decoded memory area: one for
internal boot, one for external boot, one after remap.
Boot Mode Select Option
– Non-volatile Boot Memory can be Internal or External.
– Selection is made by BMS pin sampled at reset.
Remap Command
– Allows Remapping of an Internal SRAM in Place of the Boot Non-Volatile Memory
– Allows Handling of Dynamic Exception Vectors
7.4
Peripheral DMA Controller
Transfers from/to peripheral to/from any memory space without intervention of the processor.
Next Pointer Support, forbids strong real-time constraints on buffer management.
Nineteen channels
– Two for each USART
– Two for the Debug Unit
– Two for each Serial Synchronous Controller
– Two for each Serial Peripheral Interface
– One for the Multimedia Card Interface
