The above Counter Modules have a total of 5 bytes of user data in both the
Input and Output Process Image (4 bytes of counter data and 1 byte of
control/status). The two counter values are supplied as 16 bits. The following
tables illustrate the Input and Output Process Image, which has a total of 3
words mapped into each image. Word alignment is applied.
