The above Serial Interface Modules have a total of 4 bytes of user data in both
the Input and Output Process Image (3 bytes of serial data and 1 byte of
control/status). The following table illustrates the Input and Output Process
Image, which has 2 words mapped into each image. Word alignment is
applied.
