Digital Interface Format
The device will accept audio samples in 1 of 4 digital interface formats in Stand-Alone mode, as illustrated
in Table 6, and 1 of 6 formats in Control Port mode, as illustrated in Table 7.
4.3.1
Stand-Alone Mode
The desired format is selected via the DIF1 and DIF0 pins. For an illustration of the required relationship
between the LRCK, SCLK and SDIN, see Figures 5 through 7. For all formats, SDIN is valid on the rising
edge of SCLK. Also, SCLK must have at least 32 cycles per LRCK period in format 2, and 48 cycles per
LRCK period in format 3.
4.3.2
Control Port Mode
The desired format is selected via the DIF2, DIF1 and DIF0 bits in the Mode Control 2 register (see section
Section 6.2.1). For an illustration of the required relationship between LRCK, SCLK and SDIN, see
Figures 5 through 7. For all formats, SDIN is valid on the rising edge of SCLK. Also, SCLK must have at
