System Controller MSP430
[Figure 2, callout 14]
The SP701 evaluation board implements an on-board system controller (MSP430F5342 U25)
accessible from the FT4232H USB-UART BCBUS Port D.

A host PC resident system controller user interface (SCUI) is provided on the SP701 website. This
GUI enables you to query and control select programmable features such as clocks, FMC
functionality, and power systems parameters. The SP701 documentation also includes a tutorial
on the SCUI, SP701 System Controller Tutorial (XTP551), and a SP701 Software Install and Board
Setup Tutorial (XTP552). The instructions are summarized as follows.
1. Ensure that the Silicon Labs VCP USB-UART drivers are installed. See Silicon Labs CP210x
USB-to-UART Installation Guide (UG1033).
2. Download the SCUI host PC application.
3. Connect a USB cable between your PC and the SP701 USB micro-AB connector (J5).
4. Power-cycle the SP701.
5. Ensure that SYSCTLR LED0 (D4) blinks and LED1 D5 is illuminated.
6. Launch the SCUI.
The SCUI GUI is shown in the following figure.
