11 / 26 page WM8706 Production Data w PD Rev 4.1 July 2005 11 In left justified, right justified and I 2S modes, the minimum number of BCKINs per LRCIN period is 2 times the selected word length. LRCIN must be high for a minimum of word length BCKINs and low for a minimum of word length BCKINs. Any mark to space ratio on LRCIN is acceptable provided the above requirements are met. The WM8706 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 when a LRCIN period other than 32 is detected. (see Figure 4, Figure 5 and Figure 6). In DSP early or DSP late mode, the data is time multiplexed onto DIN. 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 2 times the selected word length. Any mark to space ratio is acceptable on LRCIN provided the rising edge is correctly positioned (see Figure 7 and Figure 8). 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.
