Transmission Procedure
When the host transmits a command frame, the E5@D transmits a response frame that corresponds to
the command frame. A single response frame is returned for each command frame. The following dia-
gram shows the operation of the command and response frames.
Host
E5@D
Allow a wait time of at least 2 ms before the next command is sent after the host
receives a response from the E5@D.
