ML87V21071
2.1.8 Noise Reduction Auto Mode
The noise reduction setting value of this IC is normally register fixed mode, but considering that the noise level
may considerably exceed the set value or the noise level is almost zero, this IC is equipped with an auto mode to
automatically perform setting of noise reduction by setting NRAUTO (SUB:49h-bit[0]) and using the maximum
noise values (YMAXO[5:0], CMAXO[5:0]) and noise status signals (YDTO1, YDTO2, CDTO1, CDTO2)
detected in section 1.3.7.
When NRAUTO = 1, the auto mode of 3-status transition shown in Tables F1-3-8 (1), (2) operates. In auto mode,
any of status transition modes (auto mode 1, auto mode 2) can be selected by AMM (SUB:49h-bit[3]).
The noise reduction setting value in auto mode can be precisely set by AYABN (SUB:4Ah-bit[3]), ACABN
(SUB:4Bh-bit[3]),
AYNS[1:0]
(SUB:4Ch-bit[7:6]),
ACNS[1:0]
(SUB:4Dh-bit[7:6]),
AYLM
[1:0]
(SUB:4Eh-bit[7:6]), ACLM[1:0] (SUB:4Fh-bit[7:6]), AYMS [1:0] (SUB:50h-bit[7:6]), and AYMOFF[3:1]
(SUB:51h-bit[7:5]).
