8. Target Board

The C8051F336 Development Kit includes a target board with a C8051F338 device pre-installed for evaluation and
preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping
using the target board. Refer to Figure 3 for the locations of the various I/O connectors. Figure 4 on page 8 shows
the factory default shorting block positions. A summary of the signal names and headers is provided in Table 6 on
page 13.
