AYNS [1:0], YCNA [1:0], AYLM
[1:0], YCLM [1:0], and AYMS [1:0]
are valid. YNRM, CNRM, YABN
and CABN settings are ignored;
operation is equivalent to YNRM
= 1, CNRM = 1, YABN = 0 and
CABN = 0.
All registers other than YMS [4:0]
are the same as for the register
fixed value mode. AYMS [1:0] is
valid.
AYABN, ACABN, AYNS[1:0],
YCNS[1:0], AYLM[1:0],
YCLM[1:0], AYMS[1:0], and
AYMOFF[3:1] are valid.
