MAX5952A Evaluation Kit/Evaluation System
can be changed in the Commands | Red Hex Data
Blink Rate menu. The left status bar at the bottom of
the main window provides the CMAXQUSB interface
board status. The center status bar provides the current
EV kit and macro engine status.
When the Auto Read checkbox is checked, the program
continuously updates the main window registers and is
operating in the autoread state. In the autoread state,
data can be written to the MAX5952A by entering or
selecting the desired data in the Register Address and
Hexadecimal Data or Binary Data combo boxes.
Selecting the Write Byte button writes the combo box
data to the MAX5952A. To perform an immediate register
read, enter or choose the desired Register Address and
choose the Read Byte button. Hexadecimal or binary
data can be entered in to the Hexadecimal Data or
Binary Data combo boxes and then the alternate combo
box displays the corresponding number in the respec-
tive number base.
If the Auto Read checkbox is unchecked, the pro-
gram’s main window displays register data from the last
read. To obtain current data, a Read Byte must be per-
formed after selecting the appropriate register address
from the Register Address combo box. Autoread state
does not read the clear-on-read (COR) registers.
A macro can be run after loading the file from the File |
Open Macro menu. The opened macro is displayed in
the upper half of the Macro edit field and has an .smb file
extension. Selecting the Run button runs the macro to
completion and the output is displayed in the Macro
Script Output edit field. Each edit box can be sized rela-
tive to the other half using the splitter bar above the
Script Output text. Selecting the Single Step button
instead of the Run button causes the macro to execute a
single line with each activation of the Single Step button.
The Reset button is used to reset the macro script engine
and clear the Macro Script Output edit field. A macro
can be run regardless of the Auto Read checkbox sta-
tus. A macro can be run immediately after opening by
using the File | Open | Run Macro menu, selecting the
desired macro to run, and clicking on the Open button.
Selecting the Cancel button exits this feature.
The Locate Slave button is used to search for a
MAX5952A located on the I
interface whose address has been changed while the
software was running. The valid MAX5952A slave
address range is 0x40 through 0x5F. The MAX5952A
SMBus is a trademark of Intel Corp.

does respond to global address 0x60, although the EV
kit hardware cannot be set to this specific address.
When the Record checkbox is checked, the program
automatically enters the record macro state and dis-
ables certain buttons and menus. Choosing the
Commands | Clear Script Input menu clears any
script presently in the Macro script input edit field.
Comment lines in a macro script begin with a # / ; ‘ *
character. A line of script is entered by choosing the
appropriate Slave Address, Register Address, and
entering the desired Hexadecimal Data or Binary Data
in the combo boxes. Then selecting the Write Byte or
Read Byte button enters the script into the Macro input
edit field. For time delays in a macro, choose the
desired delay time from the combo box on the right
side of the Delay button and then select the Delay but-
ton. The macro must be saved before exiting the record
macro state, using the File | Save Macro menu. The
macro file must have an .smb file extension name.
To edit a previously saved macro, open the macro using
the File | Open Macro menu and make the desired
edits. The modified file must be saved prior to exiting the
record macro state. Uncheck the Record checkbox to
exit the record macro state. Additionally, a macro can be
created or edited using a plain text editor in text mode.
The file must be saved with an .smb extension.
There are two methods for communicating with the
MAX5952A: through the main window display or
through the general-purpose 2-wire interface utility
using the View | Interface menu. The utility configures
the I
start and stop bits, acknowledgments, and clock tim-
ing. The 2-wire interface screen allows you to send
general-purpose, I
using
WriteWord/ReadWord commands. For more informa-
tion on the differences between the I
2-wire interface and an SMBus™ interface, refer to the
Maxim Application Note Comparing the I
SMBus at www.maxim-ic.com. When using the 2-wire
utility, the main window display no longer keeps track of
changes sent to hardware. The EV kit can be reinitial-
ized to the startup screen settings by resetting the
MAX5952A using reset pushbutton S5.
