FIGURE 7. Data Input Timing.
Bit 1 is used to select the polarity of LRCIN (sample rate
clock). When bit 1 is LOW, a HIGH state on LRCIN is used
for the left channel, and a LOW state on LRCIN is used for
the right channel. When bit 1 is HIGH the polarity of LRCIN
is reversed.
Bit 2 is used to select the input word length. When bit 2 is
LOW, the input word length is set for 16 bits; when bit 2 is
HIGH, the input word length is set for 18 bits.
Bit 3 is used as an attenuation control. When bit 3 is set
HIGH, the attenuation data on Register 0 is used for both
channels, and the data in Register 1 is ignored. When bit 3
is LOW, each channel has separate attenuation data.
Bits 4 through 7 are used to determine the output format, as
shown in Table V:
