2.1.6 Target Connector Functional Check

The MSP-GANG430 GUI diagnostics support a functional check of the target connector pins. The
functional check is invoked by selecting the Target Connector category in the Maintenance group box, and
clicking the Execute button with the appropriate Set Signals defined. The Set Signals value is the decimal
value that represents the combination of the appropriate control bits. The defined pin's signal level is
available for measurement after execution of the functional check. The signal levels remain unchanged
until another configuration is set. The target connector functional check always must be terminated by
executing the End of Check setting (0x8000 = 32768) or by executing an hardware self test to initialize the
MSP-GANG430. Table 2-5

Example 1
To check the logic-high level on TDO/TDI3 and VPP voltage level on TEST/VPP:
Enter 0x040A (0x0002 + 0x0008 + 0x0400) into Set Signal and click Execute.
