Implementation of 68hc21 version 2 parts A and B Standard bit and extended bit data frames 0 to 8 bytes data length Programmable bit rate up to 1 Mbps Support for remote frames Double buffered receive Triple buffered transmit with internal prioritization using a “local priority” concept Flexible maskable identifier filter supports alternatively two full size extended identifier filter, four bit filters, or eight 8-bit filters Programmable wakeup functionality with integrated low-pass filter Programmable loopback mode supports self-test Separate signaling and interrupt capabilities for 6hc12 CAN receiver and transmitter error states warning, error passive, bus-off Programmable MSCAN clock source either the CPU bus clock or the crystal oscillator output Low-power sleep mode SAE J Byte Data Link Control Module BDLC-D The BDLC-D is an advanced serial communication multiplex bus controller operating according to the SAE J Class B protocol.
This integrated non-volatile memory solution enables: Bundled with Motorola development hardware, the MCUez development toolset includes a configuration shell, assembler, linker, and debugger.
688hc12 applications are measuring analog inputs like battery voltage, temperature, pressure, and fluid levels. Read, highlight, and take notes, across web, tablet, and phone.
Chapter topics cover an introduction to the 68HC12, 68HC12 assembly From inside the book. Multiple timer channels Each channel configurable for either input capture or output compare functions Real-time periodic interrupts Computer Operating Properly COP watchdog protection against software failures Pulse accumulator for external event counting or gated time accumulation An optional PWM offering up to four channels and up to bit PWM outputs Optional event counter system for advanced timing operations Analog-to-Digital Converter ADC The ADC periodically samples external analog signals and produces corresponding digital values.
Theory and ApplicationsSteven Frank Barrett. Typical applications of the BDLC module are in automobiles where multiple BDLC MCUs can communicate over a single or dual wire bus, eliminating the weight and bulk of wire harnesses and adding diagnostic capability. Microcontroller Theory and Applications: Storage of calibration information Self-adjusting or self-adapting systems Data logging for historical or secure data Jump tables and code patches High Performance Timer The 68HC12 timer provides flexibility, performance, and ease of use.
When used with compatible debug software such as MCUez, the SDI allows users to view and micrrocontroller applications on the fly – reducing development time and speeding time to market.
The system is based on a free-running, bit counter with a programmable prescaler, overflow interrupt, and separate function interrupts.
Low-power operation is achieved through: The MCUez toolset is designed to leverage the speed and efficient memory utilization provided by assembly language with a microcontgoller linker. SAE J compatible Prentice Hall- Computers – pages. In addition, CAN is becoming very popular for use in factory-floor automation-type industrial networks.
The SCI can be used for communications between the microcontroller and a terminal, a computer, or in network of microcontrollers. This enhanced, patented version of the Background Debug Mode found on our 68HC16 and microcontrollers replaces conventional debug modes.
