it in I2C serial bus format so that it can be directly
downloaded to the SMS45 via the programming Dongle
and cable. An example of the connection interface is
shown in Figure 8.
When design prototyping is complete, the software can
generate a HEX data file that should be transmitted to
Summit for approval. Summit will then assign a unique
customer ID to the HEX code and program production
