3.2.2 Mode 1B — SIEMaster Mode

The SIEMaster utility uses Mode 1B (see Figure 3). This utility is useful for experimenting with the

SX2 without having to write any firmware. The SIEMaster is a PC software utility, and requires a

second USB cable from the FX board to a PC (Note: you can use the same PC). The SIEMaster

utility downloads special firmware to the FX board that gives the SIEMaster utility the ability to

master the SX2 through the FX. This allows the user to read and write registers, enumerate, and

perform Endpoint 0 transfers without writing any firmware. Refer to the SIEMaster User Guide for

more details.
