Resources Uses The user connectors (CN1 and CN2) on the JOB60851 board make available to the user application system almost all onboard MSM66Q573 microcontroller pins and thus most microcontroller functionality. The JOB60851 board, however, monopolizes certain microcontroller resources in running its own system, making them unavailable to the developer.

    Figure 4.1.2. Two USB Transactions All bus transactions begin with a token packet from the host. Devices never initiate data transfers on their own. The host controller is in charge of scheduling all traffic on the bus. It schedules the appropriate transactions for the four data flow types at 1-ms intervals, which the USB documentation calls frames.

    D+ line to the 3.3-volt power supply voltage with a 1.5-k low speed does the same with the D- line. The ML60851C USB controller operates exclusively at 12 Mb/s, so the JOB60851 board includes only the D+ pull-up resistor.

  • Page 54: Special Usb Considerations

    Some systems require software control over the timing with which the USB device connects to the upstream host or hub to provide extra time for initialization and other tasks. The JOB60851 board therefore gives the microcontroller control over the D+ pull-up resistor. For further details, refer to the circuit diagram and the source code for the sample firmware.

  • Page 55: Building A Product

    4-3-5. Building a Product Generally speaking, building a product with the help of the JOB60851 board requires the following modifications and additions to the software. (1) Adding and modifying descriptors At the minimum, the source code has to provide vendor and product IDs. (See Section 4.3.6 below.) Descriptors generally also have to be modified to reflect the final product, application,...

    Japanese distributor: (2) Microcontroller emulator The JOB60851 Starter Kit provides printf(), scanf(), and other C standard I/O library functions for confirmation of operation and simple debugging of programs running on its MSM66Q573 microcontroller. Thorough debugging with program tracing and other facilities for illuminating firmware problems, however, requires an emulator (in-circuit emulator, ROM emulator, etc.)

    Chapter 4 Software Development (4) #asm and #endasm These two directives enclose an in-line assembly language block, which the compiler simply passes to the assembler. The sample firmware uses them in read_fifo() and write_fifo(), the functions for reading from and writing to USB controller buffers, and in extint1(), extint4(), and extint5(), the functions for switching register banks in response to an external interrupt from the USB controller.

    4-4. Port 7 LED2 Control The MSM66Q573 microcontroller on the JOB60851 board has twelve bidirectional ports (P0 to P11) with 75 pins and an input only port (P12). The Section describes the use of Port 7 (P7), the one connected to LED2.

  • Page 59: Changing Led2 Color

    The next page gives sample code (port7exp.c) that changes the color of the LED connected to Port 7. This sample program calls std_init_573(), a support function for initializing the MSM66Q573 on the JOB60851 board, so be sure to include the corresponding source code file (stdrw573.c) on the compiler command line.

  • Page 61: Standard I/O Over Serial Link

    4-5-1. JOB60851 Board Standard I/O The sample file stdrw573.c maps the JOB60851 board's standard input and output to a serial link joining a terminal emulator running on the host personal computer to an MSM66Q573 serial port on the JOB60851 board.

  • Page 62: Serial Port

    Serial Port Including the source code file stdrw573.c provides the user program with access to this standard I/O. This Section discusses the MSM66Q573 internal serial port that the JOB60851 board uses for this purpose, with the structure outlined in Figure 4.5.2.
  • Page 63 The serial port used for standard I/O derives its baud rate from the MSM66Q573 internal timer 3 overflow signal. The source code file stdrw573.c contains the settings for producing a 38,400- b/s baud rate from the JOB60851 board's 24-MHz system clock.
