MSM6636/6636B User’s Manual
Communication Formats
2 – 2
Y:
Address type setting bit
0 = Functional address is specified to address field (B) of receiver node.
1 = Physical address is specified to address field (B) of receiver node.
K, Z1, Z0: Sets response type
The response type is set by a combination of K, Z1 and Z0 bits.
Message type and response type are determined by the lower 4-bits of the header byte (A), including the Y bit.
Classification is shown below.
The MSM6636/6636B identify each message type and makes an automatic response.

Broadcast: The same data is transmitted to multiple responders selected by functional addressing. Only the
responder having an ID (physical address) with the highest priority can send an ID as IFR. (IFR is sent only
once, and other responder IFRs are stopped.)
*2
SAE Reserve: The MSM6636/6636B do not respond even if IFR is requested by this header, because the
response type is not defined.
