AMIS−49587
Desynchro_Request (Tag 11h)
Description: The Desynchro_Request command is used by the base micro to enforce the not synchronized state in the
AMIS−49587 and therefore it starts looking for a new synchronization.

Reset_Request (Tag 21h)
Description: The Reset_Request command is used by the base micro to ask a reset to the AMIS−49587. Then the AMIS−49587
is in Not Set mode and its data are all initialized. This command has no data. The base micro can send this command at anytime.

DATABASE
DESCRIPTION
These commands allow the access to variables in the Data Base which is constituted by a MIB array and a local data array.
The communication between the AMIS−49587 and the base micro is performed through the asynchronous serial interface
(UART) by using the WriteDB_Request, the WriteDB_Confirm and the WriteDB_Error commands.
THE COMMANDS AVAILABLE
WriteDB_Request (Tag 41h)
Description: The WriteDB_Request is sent by the base micro in order to write one data in the AMIS−49587 data base. The
field DB_Data_Id is coded on several bytes in Hex and is structured as follow:
− 2 bytes for the Identifier field (Ident) that indicates which data has to be modified (transmitted LSByte first).
− 0 to 20 bytes for the data depending on the Identifier field.
