*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.
The state diagram in Figure 30 shows how a PLC MODEM can be placed into one of the 4 main modes by issuing a
WriteConfig_Request message with accompanying configuration values. Most configuration parameters can be changed after
the MODEM is in a ‘set’ mode by the AccessDB_Request message. All settings can be undone by sending the Reset_Request
message.

Mode is changed
to Not Set
Figure 31. Sequence Diagram for Reset_Request
Use the Reset_Request to bring the MODEM in a ‘NOT SET’ mode. No power line data transmission is possible; it is as
if the MODEM comes out of reset. The MODEM does only reply with the <ACK> (=0x06) character, no additional data is
sent from the MODEM.
