CMD_IS_Indication (15h)
This command is sent by the ST7570 to external host to notify it after the MIB object 0009h
(Timeout Intelligent Synchronization, Section 6.5.10) value will be elapsed.

Description
LM_LOCKED (01h): A valid MAC frame has been received within the Intelligent
Synchronization Timeout by at least one Initiator with a MAC address within FIMA
and LIMA
LM_NOT_LOCKED (02h): A valid MAC frame has not been received within the
Intelligent Synchronization Timeout by at least one Initiator with a MAC address
0
IS_STATUS within FIMA and LIMA
LM_NOT_REGISTERED (03h): after receiving a valid MAC frame during Intelligent
Synchronization first phase, the node has not been registered (its Local MAC address
is still equal to NEW)
LM_TO_NOT_ADDRESSED (04h): after receiving a valid MAC frame during
Intelligent Synchronization first phase, the Timeout frame not addressed elapsed.
In the case the IS_STATUS is equal to LM_LOCKED, the following additional bytes are appended
1..2
ADD
Initiator MAC Address of the MAC frame received with the highest signal level during
Intelligent Synchronization first phase.
3..4
S
Max Received Signal level (between S0, S1), expressed as 100*dBµV
5.3.26
CMD_SyntaxError (20h)
This command is sent by the ST7570 to the external host after receiving a local frame with
syntax errors, meaning that at least one of the following cases has been detected:
● the value declared in the length field has not been respected in the data field
transmission
● the value declared in command code does not correspond to any command listed in
Table 15.
After the reception of a local frame with a wrong checksum field, an NAK acknowledgement
is sent.
