98 / 188 page  WM8904 Pre-Production w PP, Rev 3.3, September 2012 98 Note that the WM8904 is a 24-bit device. In 32-bit mode (AIF_WL=11), the 8 LSBs are ignored on the receiving side and not driven on the transmitting side. AUDIO INTERFACE OUTPUT TRI-STATE Register bit AIF_TRIS can be used to tri-state the audio interface pins as described in Table 55. All digital audio interface pins will be tri-stated by this function, regardless of the state of other registers which control these pin configurations. REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R25 (19h) Audio Interface 1 8 AIF_TRIS 0 Audio Interface Tristate 0 = Audio interface pins operate normally 1 = Tristate all audio interface pins Table 55 Digital Audio Interface Tri-State Control BCLK AND LRCLK CONTROL The audio interface can be programmed to operate in master mode or slave mode using the BCLK_DIR and LRCLK_DIR register bits. In master mode, the BCLK and LRCLK signals are generated by the WM8904 when any of the ADCs or DACs is enabled. In slave mode, the BCLK and LRCLK clock outputs are disabled by default to allow another digital audio interface to drive these pins. It is also possible to force the BCLK or LRCLK signals to be output using BCLK_DIR and LRCLK_DIR, allowing mixed master and slave modes. The BCLK_DIR and LRCLK_DIR fields are defined in Table 56. REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R25 (19h) Audio Interface 1 6 BCLK_DIR 0 Audio Interface BCLK Direction 0 = BCLK is input 1 = BCLK is output R26 (1Ah) Audio Interface 2 4:0 BCLK_DIV [4:0] 0_0100 BCLK Frequency (Master Mode) 00000 = SYSCLK 00001 = SYSCLK / 1.5 00010 = SYSCLK / 2 00011 = SYSCLK / 3 00100 = SYSCLK / 4 (default) 00101 = SYSCLK / 5 00110 = SYSCLK / 5.5 00111 = SYSCLK / 6 01000 = SYSCLK / 8 01001 = SYSCLK / 10 01010 = SYSCLK / 11 01011 = SYSCLK / 12 01100 = SYSCLK / 16 01101 = SYSCLK / 20 01110 = SYSCLK / 22 01111 = SYSCLK / 24 10000 = SYSCLK / 25 10001 = SYSCLK / 30 10010 = SYSCLK / 32 10011 = SYSCLK / 44 10100 = SYSCLK / 48 |
