MSP50C6xx Software Development Tool

the reset circuit and the reset pin, and connecting the scanport reset signal directly to the reset pin. See the recommended reset circuit shown in Figure 1±3.

It is also recommended that all production boards be built with the scanport interface connector footprint connected to the appropriate pins and VPP-level translator circuit shown in Figure 5±1. This allows the MSP50C6xx Software Development Tools to facilitate any post production debugging. The 10 pin connector, transistor, zenor diode, and resistors can be added as needed. The development tool must be allowed to toggle the reset pin without being loaded by any low impedance reset circuit. This can be accomplished by inserting a 1-kΩresistor between the reset circuit and the reset pin, and connecting the scanport reset signal directly to the reset pin. See the recommended reset circuit shown in Figure 1±3.

If this is not possible, it would be helpful to provide an easy way to connect the MSP50C6xx scanport pins to an external level translator circuit and scanport connector.
