The DF6811K is an advanced, 8-bit MCU IP Core with highly sophisticated, on-chip peripheral capabilities. The DF6811K has a FAST architecture, which is 4 times faster compared to the original implementation. In the standard configuration, the core has major peripheral functions integrated on-chip. An asynchronous serial communications interface (SCI) and separate synchronous serial peripheral interface (SPI), are included. The main 16-bit, freerunning timer system has three input capture and five output-compare lines, and a real-time interrupt function. An 8-bit pulse accumulator subsystem can count external events or measure external periods. Self-monitoring, on-chip circuitry is included, to protect the DF6811K against system errors. A computer operating properly (COP) watchdog system protects against software failures. An illegal opcode detection circuit provides a non-maskable interrupt, if illegal opcode is detected. Two software-controlled power-saving modes WAIT and STOP are available, to conserve additional power. These modes make the D68HC11K IP Core especially attractive for automotive and battery-driven applications. The DF6811K has a builtTM in real time hardware On-Chip Debugger DoCD , allowing easy software debugging and validation. The DF6811K is fully customizable - it is delivered in the exact configuration, to meet user’s requirements. It includes fully automated test bench with complete set of tests, allowing easy package validation at each stage of SoC design flow. The DF6811K Microcontroller Core can be used as a replacement for any of the following HC11 Microcontrollers: MC68HC(L)11K0, MC68HC(L)11K1, MC68HC(L)11K4, MC68HC11KS2, MC68HC711K4, MC68HC711KS2 and MC68HC11KW1.

This module manages execution of all instructions. The Control Unit also manages execution of STOP instruction and wakes the processor up from the STOP mode. Opcode Decoder - Performs an instruction opcode decoding and the control functions for all other blocks. ALU - Arithmetic Logic Unit performs the arithmetic and logic operations, during execution of an instruction. It contains accumulator (A), Condition Code Register (CCREG), Index registers (X) and related logic like arithmetic unit, logic unit and multiplier. Bus Controller – Program Memory, Data Memory & SFR’s (Special Function Register) interface - controls access into the program and data memories and special registers. It contains Program Counter (PC), Stack Pointer (SP) register and related logic. Interrupt Controller - extended IC has implemented 7-level interrupt priority control. The interrupt requests may come from external pin (IRQ), as well as from particular peripherals. The DF6805 peripheral systems generate maskable interrupts, which are recognized only if the global interrupt mask bit (I) in the CCR is cleared. Maskable interrupts are prioritized, according to default arrangement established during reset. When interrupt condition occurs, an interrupt status flag is set, to indicate the condition. Timer, Compare Capture & COP Watchdog – This timer system is based on a free-running, 16-bit counter, with a 4-stage programmable prescaler. 2 Copyright © 1999-2016 DCD – Digital Core Design. All Rights Reserved. All trademarks mentioned in this document are the property of their respective owners. A timer overflow function allows software to extend the timing capability of the system, beyond the 16-bit range of the counter. Three independent inputcapture functions are used, to automatically record the time, when a selected transition is detected at a respective timer input pin. Five output-compare functions are included, for generating output signals or for timing software delays. Since the input-capture and output-compare functions may not be familiar to all users, these concepts are explained in greater detail. A programmable periodic interrupt circuit called RTI is tapped off of the main 16-bit timer counter. Software can select one of four rates for the RTI, which is most commonly used to pace the execution of software routines. The COP watchdog function, is loosely related to the main timer in that the clock input to the COP system (clk*217) is tapped off the free-running counter chain. The timer subsystem involves more registers and control bits, than any other subsystem on the MCU. Each of the three input-capture functions has its own 16-bit time capture latch (input-capture register); and each of the five output-compare functions has its own 16-bit compare register. All timer functions, including the timer overflow and RTI, have their own interrupt controls and separate interrupt vectors. Additional control bits permit software, to control the edge(s), that trigger each input-capture function and the automatic actions that result from output-compare functions. Although hardwired logic is included to automate many timer activities, this timer architecture is mainly a software-oriented system. This structure is easily adaptable to a very wide range of applications, although for some specific timing applications it is not as efficient, as dedicated hardware. SCI - The SCI is a full-duplex UART type, asynchronous system, using standard non return to zero (NRZ) format : 1 start bit, 8 or 9 data bits and a 1 stop bit. The D68HC11E resynchronizes the receiver bit clock on all one to zero transitions in the bit stream. Therefore, differences in baud rate, between the sending device and the SCI, are not as likely to cause reception errors. Three logic samples are taken near the middle of data bit time and majority logic decides the sense for the bit. For the start and stop bits, seven logic samples are taken. Even if noise causes one of these samples to be incorrect, the bit will still be received correctly. The receiver also has the ability, to enter a temporary standby mode (called receiver wakeup), to ignore messages intended for a different receiver. Logic automatically wakes the receiver up, in time to see the first character of the next message. This wakeup feature greatly reduces CPU overhead in multi-drop SCI networks. The SCI transmitter can produce queued characters of idle (whole characters of all logic 1) and break (whole characters of all logic 0). In addition to the usual transmit data register empty (TDRE) status flag, this SCI also provides transmit complete (TC) indication that can be used in applications with a modem. SPI Unit – it’s a fully configurable master/slave Serial Peripheral Interface, which allows user to configure polarity and phase of serial clock signal SCK. It allows the microcontroller, to communicate with serial peripheral devices. It is also capable of interprocessor communications, in a multi-master system. A serial clock line (SCK) synchronizes shifting and sampling of the information, on the two independent serial data lines. SPI data are simultaneously transmitted and received. SPI system is flexible enough, to interface directly with numerous standard product peripherals, from several manufacturers. Data rates are as high as CLK/4. Clock control logic allows a selection of clock polarity and a choice of two fundamentally different clocking protocols, to accommodate most available synchronous serial peripheral devices. When the SPI is configured as a master, software selects one of four different bit rates for the serial clock. SPI automatically drives slave select outputs SSO[7:0] and address SPI slave device, to exchange serially shifted data. Errordetection logic is included, to support interprocessor communications. A write-collision detector indicates, when an attempt is made to write data to the serial shift register, while a transfer is in progress. A multiple-master mode-fault detector automatically disables SPI output drivers, if more than one SPI devices, simultaneously attempt to become a bus master. Pulse Accumulator – This system is based on an 8-bit counter and can be configured, to operate as a simple event counter or for gated time accumulation. Unlike the main timer, the 8-bit pulse accumulator counter can be read or written at any time (the 16-bit counter in the main timer cannot be written). Control bits allow the user, to configure and control the pulse accumulator subsystem. Two maskable interrupts are associated with the system, each having its own controls and interrupt vector. The PAI pin associated with the pulse accumulator can be configured to act as a clock (event counting mode) or as a gate signal, to enable a free-running E divided by 64 clock to the 8bit counter (gated time accumulation mode). The alternate functions of the pulse accumulator input (PAI) pin, present some interesting application possibilities. I/O Ports - All ports are 8-bit general-purpose bidirectional I/O system. The PORTA, PORTB, PORTC, PORTD data registers have their corresponding data direction registers DDRA, DDRC, DDRD to control ports data flow. It assures that all DF6811’s ports have full I/O selectable registers. Writes to any ports pins cause data to be stored in the data registers. If any port pins are configured as output, then data registers are driven out of those pins. Reads from port pins configured as input, causes that input pin is read. If port pins is configured as output, during read data register is read. Writes to any ports pins, 3 Copyright © 1999-2016 DCD – Digital Core Design. All Rights Reserved. All trademarks mentioned in this document are the property of their respective owners. not configured as outputs, do not cause data to be driven out of those pins, but the data is stored in the output registers. Thus, if the pins later become outputs, the last data written to port will be driven out the port pins. ADCCTRL – External ADC Controller, used as an interface between DF6811 internal registers and external serial/parallel ADC converter. This module has several different options, so its details are described in a separate document. EEPROMCTRL – External Serial EEPROM controller. Manage data exchange between D68HC11E and external EEPROM. During initialization copy contents of whole external EEPROM to internal EEPRAM (EEPROM Mirror implemented in standard parallel RAM).

Unlike other on-chip debuggers, DoCD™ provides non-intrusive debugging of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers, internal, external, program memories, all SFRs, including user defined peripherals. Hardware breakpoints can be set and controlled on program memory, internal and external data memories, as well as on SFRs. Hardware breakpoint is executed, if any write/read occurs at particular address, with certain data pattern or without pattern. The DoCDTM system includes three-wire interface and complete set of tools, to communicate and work with core in real time debugging. It is built as scalable unit and some features can be turned off by the user, to save silicon and reduce power consumption. When debugger is not used, it is automatically switched to power save mode. Finally, when debug option is no longer used, whole debugger is turned off. The separate CLKDOCD clock line allows the debugger to operate, while the CPU is in STOP mode and the major clock line CLK is stopped.
