Download Motorola 68HC11 Microcontroller: Four Designs and Implementation and more Study notes Microprocessors in PDF only on Docsity! Circle the Correct Answer Introduction The report presents four designs that demonstrate some of the input, output, and programming capabilities of the Motorola 68HC11 microcontroller. These designs made use of the HC11’s input Port A and output Port B…. As shown in Figure 1, the hardware (consisted / consists / will consist) of the DIP switches connected to Port A of the HC11 and the hex display connected to Port B. In addition, the hardware design (included / includes / will include) a serial connection between the HC11 and a personal computer (PC) for downloading the assembled programs into the HC11. To implement the hardware, we (used / use / will use) the assembly software package (DevHC11) installed on the PC…. Section 1: Assembling a Program The first design (called / calls / will call) for writing a program, assembling it, loading it into the HC11 memory, and then running the program to verify (its / it’s / its’) operation… The work for this section (was divided / is divided / will be divided) between my partner and (I / me) in the following way.… Section 2: Operating in the Standalone Mode For the second design, the HC11 (was required / is required / will be required) to run in the standalone mode. In general, operating in the standalone mode (meant / means / will mean) that…For this particular laboratory, operating in the standalone mode (meant / means / will mean)… Procedures for Design Because there (were / are / will be) no hardware modifications from the first design of the laboratory, this second design (consisted / consists /will consist) solely of software design….The program code, shown in Appendix C, (consisted / consists / will consist) of two subroutines….We had to mask out PA1 so that the pin’s value did not (affect / effect) the output…. Conclusion This report (presented / has presented / presents / will present) four designs for the HC11 microcontroller…
