Hardware Debugging Enhancements 10BaseT Ethernet � MAC and Phy Analog part is external 8 DMA Channels Four PWM Channels Among the debugging enhancements is the implementation of seven hardware breakpoint registers.

8. Major Features/Subsystems Two Quadrature Decoder Channels Two Input Capture Channels Slave Port Interface Six External Interrupt Inputs External I/O Interface Built-in Real Time Clock Two Watchdog Timers

9. Parallel PortsSummary Port Pins shared among the Peripheral Devices On reset all bits which can be inputs are set as inputs. Ports B, C, D & E: each bit is individually configurable as either input or output. Ports C, D & E: each output bit is individually configurable as either push-pull or open drain. It is extremely important that a system designer understand the details of the Rabbit�s parallel I/O ports. Since most of the ports have multiple personalities the designer must decide �up front� how each port is to be used.

10. Parallel PortsPort C Alternate Outputs I0-I7 are the I/O strobes for External I/O The alternate outputs are selected via PCFR, PCAHR and PCALR I0-I7 are the I/O strobes for External I/O The alternate outputs are selected via PCFR, PCAHR and PCALR

11. Parallel PortsPort C Inputs Note that input ports can be used by more than one peripheral at the same time; ie, PC7 can be used by InputCapture, as RxA and RxE simultaneously.Note that input ports can be used by more than one peripheral at the same time; ie, PC7 can be used by InputCapture, as RxA and RxE simultaneously.

12. Rabbit Configuration Utility Supports only the Rabbit 4000 Presents a GUI for configuring the Rabbit 4000 I/O features Is sensitive to shared processor resources � it does NOT know about Core Modules Creates a library file based on user�s selections

22. DMA 8 identical and independent channels Transfer data between any two of Memory External I/O Internal I/O Two external signals may be used for flow control Each channel has its own interrupt

23. DMA Buffer Descriptors are used to control DMA operation Operate from DMA registers but may originate in memory Several buffer modes Single Buffer Array of Buffers Linked List Circular Queue Linked Array

24. DMA Program determines how much CPU time is allocated to DMA transfers Bytes per burst CPU clocks between bursts Transfer priority

25. External Interrupts Two Interrupt Vectors (ISRs) with 3 input sources each Three bit low pass filter Maximum Interrupt Latency = 29 clocks Interrupt on rising and/or falling edge(s) No action required to clear the interrupt

26. External I/O Easy method of adding parallel ports Chip designs have access to 13 address bits for a total of 64K bytes RCM designs allow Auxiliary External I/O Access 6 or 8 address lines Uses Port A as the data bus Handshake inputs to pause transactions
