memory location Each M68HC12 memory location holds byte data unique address. store information memory location, places address location address bus, data information data bus, asserts write signal. read information from memory location, places address location address asserts read signal. response read signal, selected memory location places data onto data bus. memory pictorial representation memory locations computer system. MI-Bus "Motorola interconnect bus". microcontroller Microcontroller unit (MCU). complete computer system, including CPU, memory, clock oscillator, input/output (I/O) single integrated circuit. modulo counter counter that programmed count number from zero maximum possible modulus. most significant (MSB) leftmost digit binary number. Motorola interconnect (MI-Bus) Motorola Interconnect Bus) serial communications protocol which supports distributed real-time control efficiently with high degree noise immunity. Motorola scalable (msCAN) Motorola scalable controller area network serial communications protocol that efficiently supports distributed real-time control with very high level data integrity. msCAN "Motorola scalable CAN". "multiple serial interface". multiple serial interface module consisting multiple independent serial sub-systems, e.g. SPI. multiplexer device that select number inputs pass logic level that input output. nibble four bits (half byte). object code output from assembler compiler that itself executable machine code, suitable processing produce executable machine code. opcode binary code that instructs perform operation. open-drain output that pullup transistor. external pullup device connected power supply provide logic output voltage.

operand Data which operation performed. Usually statement consists operator operand. example, operator instruction, operand quantity added. oscillator circuit that produces constant frequency square wave that used computer timing sequencing reference. OTPROM One-time programmable read-only memory. nonvolatile type memory that cannot reprogrammed. overflow quantity that large contained byte word. page zero first bytes memory (addresses $0000-$00FF). parity error-checking scheme that counts number logic each byte transmitted. system that uses parity, every byte expected have number logic even parity system, every byte should have even number logic transmitter, parity generator appends extra each byte make number logic parity even even parity. parity checker receiver counts number logic each byte. parity checker generates error signal finds byte with incorrect number logic "program counter (PC)." peripheral circuit under direct control. phase-locked loop (PLL) clock generator circuit which voltage controlled oscillator produces oscillation which synchronized reference signal. "phase-locked loop (PLL)." pointer Pointer register. index register sometimes called pointer register because contents used calculation address operand, therefore points operand. polarity opposite logic levels, logic logic which correspond different voltage levels, VSS. polling Periodically reading status monitor condition peripheral device. port wires communicating with off-chip devices. prescaler circuit that generates output signal related input signal fractional scale factor such 1/2, 1/8, 1/10 etc. program computer instructions that cause computer perform desired operation operations.

program counter (PC) 16-bit register CPU. register holds address next instruction operand that will use. pull instruction that copies into accumulator contents stack location. stack address stack pointer. pullup transistor output logic gate that connects output logic voltage power supply. pulse-width amount time signal opposed being state. pulse-width modulation (PWM) Controlled variation (modulation) pulse width signal with constant frequency. push instruction that copies contents accumulator stack RAM. stack address stack pointer. period time required complete cycle waveform. Random access memory. locations read written CPU. contents memory location remain valid until writes different value until power turned off. circuit circuit consisting capacitors resistors having defined time constant. read copy contents memory location accumulator. register circuit that stores group bits. reserved memory location memory location that used only special factory test modes. Writing reserved location effect. Reading reserved location returns unpredictable value. reset force device known condition. "serial communication interface module (SCI)." serial Pertaining sequential transmission over single line. serial communications interface module (SCI) module that supports asynchronous communication. serial peripheral interface module (SPI) module that supports synchronous communication. change from logic logic opposite clear.

shift register chain circuits that retain logic levels (logic logic written them that shift logic levels right left through adjacent circuits chain. signed binary number notation that accommodates both positive negative numbers. most significant used indicate whether number positive negative, normally logic positive logic negative. other seven bits indicate magnitude number. software Instructions data that control operation microcontroller. software interrupt (SWI) instruction that causes interrupt associated vector fetch. "serial peripheral interface module (SPI)." stack portion reserved storage register contents subroutine return addresses. stack pointer (SP) 16-bit register containing address next available storage location stack. start that signals beginning asynchronous serial transmission. status register that indicates condition device. stop that signals asynchronous serial transmission. subroutine sequence instructions used more than once course program. last instruction subroutine return from subroutine (RTS) instruction. each place main program where subroutine instructions needed, jump branch subroutine (JSR BSR) instruction used call subroutine. leaves flow main program execute instructions subroutine. When instruction executed, returns main program where left off. synchronous Refers logic circuits operations that synchronized common reference signal. timer module used relate events system point time. toggle change state output from logic logic from logic logic tracking mode mode operation with narrow loop bandwidth. Also `acquisition mode.'

two's complement means performing binary subtraction using addition techniques. most significant two's complement number indicates sign number indicates negative). two's complement negative number obtained inverting each number then adding result. unbuffered Utilizes only register data; data overwrites current data. unimplemented memory location memory location that used. Writing unimplemented location effect. Reading unimplemented location returns unpredictable value. variable value that changes during course program execution. "voltage-controlled oscillator." vector memory location that contains address beginning subroutine written service interrupt reset. voltage-controlled oscillator (VCO) circuit that produces oscillating output signal frequency that controlled voltage applied control input. waveform graphical representation which amplitude wave plotted against time. wired-OR Connection circuit outputs that output high, connection point high. word bytes bits). write transfer byte data from memory location.
