hc11 microcontroller manual

Used: Very GoodPlease try again.Please try again.Please try again. Detailed descriptions of all internal subsystems and functions have been developed and carefully checked against internal Motorola design documentation, making this manual the most comprehensive reference available for the M68HC11 Family of microcontroller units (MCUs). Practical applications are included to demonstrate the operation of each subsystem.Then you can start reading Kindle books on your smartphone, tablet, or computer - no Kindle device required. Register a free business account To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness. Feel free to customize it for your page.Motorola provides datasheets and reference manuals for this processor, which we also provide here for your convenient download. These manuals are valuable aids in the development of M68HC11 applications as they provide detailed descriptions of all internal subsystems and functions. It is a CISC microcontroller. The 68HC11 devices are more powerful and more expensive than the 68HC08 microcontrollers, and are used in automotive applications, barcode readers, hotel card key writers, amateur robotics, and various other embedded systems.It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a 16-bit stack pointer, and a program counter. A range of 16-bit instructions treat the A and B registers as a combined 16-bit D register for comparison (X and Y registers may also be compared to 16-bit memory operands), addition, subtraction and shift operations, or can add the B accumulator to the X or Y index registers.http://www.popnmusic.fr/userfiles/grundig-dtr-8740-manual.xml

Bit test operations have also been added, performing a logical AND function between operands, setting the correct conditions codes, but not modifying the operands.The most common version has five ports, A, B, C, D, and E, but some have as few as 3 ports (version D3). Each port is eight-bits wide except for D, which is six bits (in some variations of the chip, D also has eight bits). It can be operated with an internal program and RAM (1 to 768 bytes) or an external memory of up to 64 kilobytes. With external memory, B and C are used as address and data bus. In this mode, port C is multiplexed to carry both the lower byte of the address and data.BUFFALO is available for most 68HC11 family derivatives as it generally only depends upon having access to a single UART (SCI, or Serial Communications Interface, in Motorola parlance). BUFFALO can also run on devices that do not have internal non-volatile memory, such as the 68HC11A0, A1, E0, E1, and F1 derivatives.Retrieved 2020-04-08.
