Each can hold 252 bytes of user binary data. That 252 bytes (or less) of user data, with
a 4 byte prefix (for a total of 256 bytes) can be provided with the --in=FN option. A
typical prefix would be '0,n,83,fc'. The "n" is the parameter code in hex so the last log
parameter would be '0,3f,83,fc'. That log parameter could be read back at some later
time with '--page=0xf --filter=0x<n>'
