Types of Packets
Packets TMC2084 Can Receive
TMC2084 can receive the three types of packets from the host node: the Initial Setting, Command and
OUTPUT DATA packets. The packet is identified using the packet ID code included in the first data byte
(DATA0) of it and any packet that has undefined code is discarded.
Packet’s RAM image on the host node is shown below.
