The field definitions for RCRR on page 1-4 do not match the field definitions for INSERT.RCRR on page 3-118. r~

I guess it is confusing that RCRR on page 1-4 uses s1, s2, etc., and d for the reg names, while INSERT.RCRR on page 3-118 enumerates the reg names from a to d. So the "d" for dst from page 1-4 is not the same "d" on page 3-118. Cheers, Bastian
