There was a problem hiding this comment.
How about reading from _1 to _4 but shift the data position first and | with return value for each reading, something like below?
data = (data<<8)|((u32)(ret&0xff))

Attribute is show all present result like 0xFFFF from port1 to port 32.

instead of moving ret value with different shifting value, shifting the data 8bit to the left each time before or-ing the ret value will give same shifting for each ret value. then only 8bit shifter not three different shifter (8bit, 16bit, and 24bit).

you can make it more simpler with macro definition too.

but this is recommendation not blocking
