5. 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 4 for the locations of the various I/O connectors. Figure 5 on page 7 shows
the factory default shorting block positions. A summary of the signal names and headers is provided in Table 6 on
page 12.
