minimum of word length BCKINs. Any mark to space ratio on LRCIN is acceptable provided the above
requirements are met. The WM8756 will automatically detect when data with a LRCIN period of exactly 32
is sent, and select 16 bit mode - overriding any previously programmed word length. Word length will
revert to the previously programmed value if a LRCIN period other than 32 is detected.
In DSP early or DSP late mode, all 6 channels are time multiplexed onto DIN0. LRCIN is used as a frame
sync signal to identify the MSB of the first word. The minimum number of BCKINs per LRCIN period is 6
times the selected word length. Any mark to space ratio is acceptable on LRCIN provided the rising edge
is correctly positioned (see Figures 9 and 10).
LEFT JUSTIFIED MODE
In left justified mode, the MSB is sampled on the first rising edge of BCKIN following a LRCIN transition.
LRCIN is high during the left samples and low during the right samples.
