7-9-3 Outline of Protocol Macro Function
H
Protocol Macro Function
·
The protocol macro function makes it possible to customize a communications proto-
col in order to create a macro according to the specifications of the serial communica-
tions port of the general-purpose peripheral device.
·
The protocol macro function is mainly used for the following jobs.
Creation of message communications frame.
Creation of Send & Recv procedures for message communications frame.
Note
This manual uses the terms “message, DSR message, and response” to express
