    Can't they both be right ?
    The 16 bit field has no 0 mapping, so the number is 1..2^16, instead of 0..2^16-1 ?

    The old instruction set used the Z effect bit in REPS as the 17th bit.
    Last time I checked 2^16 = 65536 not 131072. :)

    Edit: PNUT only allows 1 to 65536 as values for REPS

    I think your highlights of blue and green text are OK, and the red is a simple cut/paste legacy typo.
    When reading such texts, I tend to ignore the comments above the opcodes, and skip to the opcode encoding, but for accuracy the comments should ideally match the opcode lines they refer to.
    Fix : trim n_ you have in red ?

    Personally, I tend to read what others contribute, try and understand their intent and work from there, but that's just me. :)
