DK101 Low-Cost Demo Kit Motherboard
BASIC OPERATION
Hardware Configuration
Connecting a Daughter Card. Plug the daughter card into the DK101’s connectors. The daughter card should be
oriented as shown in Figure 1. Note that some daughter cards have a third connector for advanced features
(UTOPIA bus, POS-PHY bus, etc.). The DK101 is compatible with three-connector daughter cards, but does not
support the advanced features available on the third connector. These advanced features are supported on Dallas’
high-end demo kit platform, DK2000. When present, the third connector is located to the left of the other two
connectors (when oriented as shown in Figure 1). Note that daughter cards are not designed for hot insertion. Only
connect daughter cards to the DK101 motherboard with the power off.
Power Supply Connections. Connect a 3.3V power supply across the red (VCC 3.3V) and black (GND) banana
jacks. The green PWR LED should be lit to indicate power is applied to the board. The TIM STATUS LED should
be green to indicate that the DK101 recognizes the attached daughter card. If TIM STATUS is red, the DK101 is
not properly connected to the daughter card or does not recognize the daughter card.
If the daughter card has a device that requires a 5V supply, do one of the following:
1) To use the DK101’s on-board DC-DC converter (max current = 1A), set the three-position jumper marked
TIM 5V SUPPLY to BOOST CONVERTER.
2) To use an external 5V power supply, set the TIM 5V SUPPLY jumper to EXTERNAL and connect the
external power supply across the red EXTERNAL 5V and black GND jacks.
Connecting to a Computer. Connect a standard DB-9 serial cable between the serial port on the DK101 and an
®
available serial port on the host computer. The host computer must be a Windows -based PC. Be sure the cable is
a standard straight-through cable rather than a null-modem cable. Null-modem cables prevent proper operation.
Setting the DIP Switches. For basic operation, use the following settings:
· Switch number 1 OFF (flash program voltage not applied).
· Switches 2 through 4 ON (8-bit daughter card; boot internal; run kit firmware).
· Switches 5 through 8 do not affect operation of the kit firmware.
Installing the ChipView Software
To install the demo software on the host PC, run SETUP.EXE on the demo kit CD-ROM (or from the .ZIP file
downloaded from the our website, www.maxim-ic.com/telecom). Follow the instructions given by the SETUP
program. By default, SETUP installs the application software in “C:\Program Files\ChipView” and creates a shortcut
in the ChipView program group.
Running the ChipView Software
Run the ChipView application. If the default installation options were used, click the Start button on the Windows
toolbar and select Programs®ChipView®ChipView. The main menu window provides three options: Register
View, Demo, and Terminal Mode. Register View mode and Demo mode are discussed in the following paragraphs.
Terminal mode is discussed in the Advanced Features section.
Register View Mode
Register View provides an intuitive user interface for reading, writing, and viewing the IC registers on the daughter
card. Register bytes and bits are displayed by name in an on-screen array. Values can be read or written with a
click of the mouse. Figure 2 shows an example of the Register View window.
To go to Register View from the ChipView main menu window, follow these steps:
1) Push the Register View button in the main menu window. A popup window for COM port selection
appears next. Select the appropriate port from the menu and click OK. Next, the Definition File
Assignment window appears. This window has subwindows to select definition files for up to four
separate daughter cards. Because the DK101 platform only interfaces with one daughter card at a
time, only one subwindow is active.
Windows is a registered trademark of Microsoft Corp.

DK101 Low-Cost Demo Kit Motherboard
2) Select a definition file from the list shown, or browse to find a file in another directory.
Typically definition file names contain the device name, e.g., DS2155.def. Some daughter
cards ship with multiple definition files. See the daughter card data sheet for detailed
information on the use of the various files.
3) Press the Continue button.
The main part of the Register View window displays the register map. To select a register, click on it in the register
map. When a register is selected, the full name of the register and its bit map are displayed at the bottom of the
Register View window. Bits that are logic 0 are displayed in white, while bits that are logic 1 are displayed in green.
The Register View interface supports the following actions:
·
·
·
·
·
Toggle a bit. Select the register in the register map and then click the bit in the bit map.
Write a register. Select the register, click the Write button, and enter the value to be written.
Write all registers. Click the Write All button and enter the value to be written.
Read a register. Select the register in the register map and click the Read button.
Read all registers. Click the Read All button.
When the Read or Read All buttons are selected, registers whose values have changed since last read are
highlighted in green. This highlighting can be disabled by unchecking the Options®Highlight Changed Registers
menu selection.
Multiple definition files can be loaded at the same time to control different portions of the daughter card hardware.
To load an additional definition file, select File®Definition File. In the Definition File Assignment window, select the
appropriate file and press the Continue button. The Register View window now shows the view defined by the new
definition file. Use the pulldown menu below the command buttons to switch between definition file views. See the
Advanced Features section for information about creating and editing definition files.
To go to Register View from other views, select Windows®Go to Register View.

Demo Mode
Demo mode provides an intuitive user interface for configuring daughter cards at a high level using option buttons
and menu selections. Key status information is also displayed, such as LOS, OOF, and AIS. Figure 3 shows an
example of the Demo window.
To go to the Demo window from the ChipView main menu window, follow these steps:
1) Push the Demo button in the main menu window. A popup window for COM port selection appears
next. Select the appropriate port from the menu and click OK. Next, the Configuration File Assignment
window appears. This window has subwindows to select configuration files for up to four separate
daughter cards. Because the DK101 platform only interfaces with one daughter card at a time, only
one subwindow is active.
2) Select a configuration file in the active subwindow from the list shown, or browse to find a file
in another directory. Typically configuration file names contain the device name, e.g.
DS2155.cfg. Some daughter cards ship with multiple configuration files. See the daughter
card data sheet for detailed information on the use of the various files.
3) Press the Continue button.
The Demo window shows various daughter-card-specific configuration menus and status indicators. See the
daughter card data sheet for details about the specific menus, selections, and indicators used. The Com Status
indicator, which is common to most configuration files, changes state approximately once a second when the
ChipView software is communicating properly with the daughter card.

ADVANCED FEATURES
This section discusses several advanced features of the DK101 platform. Many DK101 users do not need to read
this information. The DK101 and Dallas daughter cards ship with full definition files for Register View mode and one
or more configuration files for Demo mode. These files support most users very well without any need for
customization. For users with more complex requirements, however, this section describes how to:
·
·
·
·
Create and edit definition (.DEF) files
Create and edit initialization (.INI) files
Use Terminal mode
Download and execute custom firmware
Creating and Editing Definition (.DEF) Files
Definition files are ASCII text files that specify register names, addresses, and bit fields, and their arrangement in
the Register View window. Dallas Semiconductor distributes full definition files with each daughter card. Any edits
to the Dallas definition files should be made in copies of the files and not in the originals.
The text in Figure 4 is a definition file template. Only the REGISTER, DISPLAY and END fields are required. Each
field starts with the field name followed by a colon (i.e., “DEVICE:”) and ends with the next field name. The
definition file fields are described in Table 1. All numbers are in decimal format, unless otherwise stated.

Table 1. Definition File Fields
FIELD
REM
DESCRIPTION
Used for remarks to document the definition file. Cannot be used inside another field.
This field is not yet supported in the ChipView software.
DEVICE
The argument is a string of text that is displayed at the top of the Register View screen to help the user keep
track of which definition file is currently in use.
When located outside the REGISTER field, the argument specifies a global address offset for all registers in
the definition file. In some Dallas-made definition files OFFSET has two arguments. Older Dallas demo kit
software selects the first argument. The ChipView software selects the last argument.
OFFSET
When located inside the REGISTER field, the argument specifies a local address offset for all subsequent
register listings. All register addresses following the local OFFSET field are offset by both the global and local
offsets. The scope of the local offset is to the end of the REGISTER field or to the next local offset field.
LINKS
SETUP
REG INI
DEVICE ID
REGISTER
Arguments are in four-digit hexadecimal format of the form “0x0000.”
Loads additional definition files. Used to accommodate more than one device on a piece of hardware or to split
a large register set into smaller subsets. The first argument is a number from 1 to 10 specifying the number of
definition files to link. Subsequent arguments are the filenames of the definition files being linked. Linked
definition files have all the functionality of the main definition file except that the LINKS field is ignored.
This field is not yet supported in the ChipView software.
Enables initialization register values. The argument must be either “on” or “off.” If the argument is “on,”
ChipView initializes all registers with a zero and then the initial value specified in the REGISTER field. When
SETUP is “on” the REG INI field is enabled.
This field is not yet supported in the ChipView software.
Specifies an initialization file for initializing register values. REG INI is only enabled if the SETUP field is “on.”
The first argument must be either “on” or “off.” The second argument is a valid register initialization file (.INI
file). If the SETUP and REG INI fields are both “on,” registers are initialized by the values in the initialization
file.
This field is not yet supported in the ChipView software.
Defines how to determine if the device is present on the target hardware. The first argument must be either
“on” or “off.” The second argument is a valid register description (see the REGISTER field for format). If the first
argument is “on” the ChipView software performs a device-check read/write sequence to the register specified
in the second argument. If the device check fails, a Device Not Present error is displayed.
Describes the registers of the target hardware. The first argument is the number of registers (1 to 255).
Subsequent arguments are comma-delimited strings with 14 subfields as follows:
address,rname,rtype,bus,ivalue,position,fullname,b7,b6,b5,b4,b3,b2,b1,b0,
The number of strings must be equal to the number of registers specified in the first argument. See Table 2 for
subfield definitions.
This field is not yet supported in the ChipView software. Currently, registers are displayed 14 per column in the
order listed in the REGISTER field.
DISPLAY
END
Specifies how to display the registers on screen. The first argument is a number from 1 to 20 that states the
number of columns to be displayed. Subsequent arguments are comma-delimited strings of numbers, where
each number specifies a register definition. The first register definition in the REGISTER field is 0, the second
is 1, and so on. The strings of numbers can be up to 14 numbers long. The number of strings must be equal to
the number of columns specified in the first argument.
Specifies the end of the definition file. This field has no arguments.

Initial value written to the register during initialization if the SETUP field is “on.” Two-digit hexadecimal
format of the form “00.”
Register position. Allows the user to sequentially number the register definitions for use in the DISPLAY
field. These numbers are for the user only; this field is not read by the software. For proper use with the
DISPLAY field, register definitions should be numbered consecutively starting from 0 with no missing or
repeated numbers.
Full register name. A string of £ 50 characters that is displayed at the top of the bitmap display when the
register is selected in the register map.
Bit names. Each is a string of £ 6 characters that is displayed in the bit map display.
Creating and Editing Initialization (.INI) Files
Register View mode provides an easy method for initializing an entire register set using initialization files. To
initialize the register set from an initialization file, choose File®Register .INI File®Load .INI File. To save the state
of a register set to an initialization file, choose File®Register .INI File®Build .INI File. Only the registers of the
active definition file are affected by these commands.
Terminal Mode
In addition to Register View mode and Demo mode, the ChipView software also offers Terminal mode, which gives
direct access to the processor. The commands that can be entered from Terminal mode are listed in Table 3. The
interface specifications are 57,600 baud, 8 data bits, 1 stop bit, no parity, no flow control, ANSI emulation. Locally
typed characters are echoed by the DK101, not the terminal software.
Downloading and Executing Custom Firmware
To download and execute custom firmware on the DK101, do the following:
1) Create a Motorola s-record targeted to external SRAM at 80000000h.
2) Go to Terminal mode on the ChipView software.
3) Click Options®Load S Record.
4) Browse to find the appropriate s-record, select it, and click Open.
5) Wait while the s-record is downloaded to the DK101.
6) Type the “jump” command and hit the Enter key.
To return to the factory-installed DK101 firmware, press the RESET button on the DK101 board.

The DK101 firmware includes T1/E1 device driver code written by NComm. CTRL
calls the TE1DCTRL device driver API with the indicated parameters (see T1/E1
driver code documentation for details). The slot number on the end is not passed
through to the API but is simply used to determine which device driver to call.
Example: CTRL 0 400 0 {resets span 0 of slot 0}
POLL <…> <slot>
The DK101 firmware includes T1/E1 device driver code written by NComm. POLL
calls the TE1DPOLL device driver API with the indicated parameters (see T1/E1
driver code documentation for details). The slot number on the end is not passed
through to the API but is simply used to determine which device driver to call.
Example: POLL 0 600 0 {polls for RLOS on span 0 of slot 0}

APPENDIX
MMC2107 CPU and Memory Map
CPU Core. The DK101 development platform is based on the Motorola MMC2107 MCORE processor. The DK101
is configured with an 8MHz oscillator that is internally multiplied inside the processor to 32MHz.
Internal Flash. The MMC2107 has 128kB of internal flash memory organized as 32-bit words.
Internal SRAM. The MMC2107 has 8kB of internal SRAM organized as 32-bit words.
External SRAM. The DK101 has 256kB of external SRAM organized as 128kB x 16 and connected to chip select 0
(CS0) of the MMC2107.
Chip Selects and Memory Map. The MMC2107 has four chip-select outputs. The DK101 board uses these chip
selects as defined in Table 4.
