Manufacturer Information
4287C–USB–11/04
The purpose of this process is to manage the communication and its protocol between
the on-chip bootloader and an external device (host). The on-chip bootloader imple-
ments a USB protocol (see section “Protocol”). This process translates serial
communication frames (USB) into Flash memory accesses (read, write, erase...).
Several Application Program Interface (API) calls are available to the application pro-
gram to selectively erase and program Flash pages. All calls are made through a
common interface (API calls) included in the bootloader. The purpose of this process is
to translate the application request into internal Flash memory operations.
This process manages low level access to the Flash memory (performs read and write
access).
The table below lists Configuration and Manufacturer byte information used by the boot-
loader. This information can be accessed through a set of API or ISP commands.
