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 implements a CAN proto-
col (see Section “Protocol”, page 10). This process translates serial communication frames
(CAN) into Flash memory accesses (read, write, erase...).
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 accesses to the Flash memory (performs read and write
accesses).
The following table lists Configuration and Manufacturer byte information used by the boot-
loader. This information can be accessed through a set of API or ISP commands.
