5.1.3 Download SDO Protocol

Initiate SDO Download Protocol

The download modes are similar to the upload modes, but different in

some parameters of the SDO messages. They are also separated into two

steps. If the download data length is less than 4 bytes, the download action will

finish in the download initialization protocol. Otherwise, the download segment

protocol will be needed. These two protocols are shown below.
