*An unsolicited message is a message that is originating from the AMIS49587, based upon an AMIS49587 internal event. The message is
not provoked by a prior command sent by the external processor.
7.5.1 AccessDB_Request
The AccessDB_Request command can be used to read data path statistical information from the AMIS49587.
Like in all other AccessDB_Request commands, the specific identifier of the data that is to be read needs to be provided:
Field Name
Identifier
Description
Invalidframecounter
0x0006
Read the value of the invalidframe counter and then set to 0
Counters
0x000D
Read the value of the data counters:Counter Crc Ok, Counter Crc Not Ok,
Repeater counter, Transmit counter, corrected frames counter, and then
set to 0 or not
DataStats
0x0010
Read the value of the Data statistics, and then set to 0 or not.
7.5.1.1 Invalid Frame Counter
This request is used to read the Invalid Frame Counter of the AMIS49587. Once the request sent to the AMIS49587, the
Invalid Frame counter is automatically set to 0. The AMIS49587 answers with the value of the Invalid Frame Counter
