WINDOWS GUI USERS GUIDE AND CONFIGURATION REGISTER DESCRIPTIONS

Download this entire Applications Note in PDF format.

Introduction The information contained in Application Note 28 details the Configuration Register settings for the SMT4214 expandable power supply tracking manager. The SMT4214 Windows Graphical User Interface (GUI) is also shown with the associated register and function highlighted. For additional explanation on device functionality related to the configuration registers, also refer to the SMT4214 Data Sheet. Register Formats and Functions There are a total of 7 Configuration Registers that are separated into five basic register types. The first are those that set a monitoring threshold where the binary value written to the register is multiplied times a base incremental voltage. The second type enables or disables a function or selects between two specific functions. The third register type allows selection of various timeout intervals or voltage values. These are not incremental, like the thresholds, but specific bit patterns select specific timer or voltage values. The fourth register type are volatile status registers that record device conditions. The fifth register type is a volatile Read/Write register that allows I2C software power-on or power-off control of all SMT4214 channels. All Write and Read operations use the 1001b slave address.

  

 

SMT4214 Windows Graphical User Interface

The SMT4214 Windows GUI (Figure 1) is used with the SMX3200 programming 'Dongle'. It is an easy to use Graphical Interface that is compatible with Windows 95, 98, NT, 2000 and XP operating systems. The GUI consists of pull-down menus, check boxes, up/down buttons, etc.. There are "mouse-overs" that define every function and an expert mode for directly entering data into the configuration registers. The GUI generates a checksum that can compare the programmed device configuration register values versus the hex contents.
